- Factor Analysis - Used to identify the underlying variables, or factors, that explain the pattern of correlations within a set of observed variables. In IBM SPSS Statistics Base, the factor analysis procedure provides a high degree of flexibility, offering:
- Seven methods of factor extraction
- Five methods of rotation, including direct oblimin and promax for nonorthogonal rotations
- Three methods of computing factor scores. Also, scores can be saved as variables for further analysis
- K-means Cluster Analysis - Used to identify relatively homogeneous groups of cases based on selected characteristics, using an algorithm that can handle large numbers of cases but which requires you to specify the number of clusters. Select one of two methods for classifying cases, either updating cluster centers iteratively or classifying only.
- Hierarchical Cluster Analysis - Used to identify relatively homogeneous groups of cases (or variables) based on selected characteristics, using an algorithm that starts with each case in a separate cluster and combines clusters until only one is left.

IBM Advanced Statistics - More Accurately Analyze Complex Relationships Using Powerful Univariate and Multivariate Analysis
General linear models (GLM) – Provides you with more flexibility to describe the relationship between a dependent variable and a set of independent variables. The GLM gives you flexible design and contrast options to estimate means and variances and to test and predict means. You can also mix and match categorical and continuous predictors to build models. Because GLM doesn't limit you to one data type, you have options that provide you with a wealth of model-building possibilities.
- Linear mixed models, also known as hierarchical linear models (HLM)
The linear mixed models procedure expands the general linear models used in the GLM procedure so that you can analyze data that exhibit correlation and non-constant variability. If you work with data that display correlation and non-constant variability, such as data that represent students nested within classrooms or consumers nested within families, use the linear mixed models procedure to model means, variances and covariances in your data.
- Fixed effect analysis of variance (ANOVA), analysis of covariance (ANOVA), multivariate analysis of variance (MANOVA) and multivariate analysis of covariance (MANCOVA)
- Random or mixed ANOVA and ANCOVA
- Repeated measures ANOVA and MANOVA
- Variance component estimation (VARCOMP)
Its flexibility means you can formulate dozens of models, including split-plot design, multi-level models with fixed-effects covariance, and randomized complete blocks design. You can also select from 11 non-spatial covariance types, including first-order ante-dependence, heterogeneous, and first-order autoregressive. You'll reach more accurate predictive models because it takes the hierarchical structure of your data into account.
You can also use linear mixed models if you're working with repeated measures data, including situations in which there are different numbers of repeated measurements, different intervals for different cases, or both. Unlike standard methods, linear mixed models use all your data and give you a more accurate analysis.
- Generalized linear models (GENLIN): GENLIN covers not only widely used statistical models, such as linear regression for normally distributed responses, logistic models for binary data, and loglinear model for count data, but also many useful statistical models via its very general model formulation. The independence assumption, however, prohibits generalized linear models from being applied to correlated data.
- Generalized estimating equations (GEE): GEE extend generalized linear models to accommodate correlated longitudinal data and clustered data.
- General models of multiway contingency tables (LOGLINEAR)
- Hierarchical loglinear models for multiway contingency tables (HILOLINEAR)
- Loglinear and logit models to count data by means of a generalized linear models approach (GENLOG)
- Survival analysis procedures:
- Cox regression with time-dependent covariates
- Life Tables
IBM SPSS Regression Overview, Features and Benefits
More Statistics for Data Analysis
Expand the capabilities of IBM® SPSS® Statistics Base for the data analysis stage in the analytical process. Using IBM SPSS Regression with IBM SPSS Statistics Base gives you an even wider range of statistics so you can get the most accurate response for specific data types.
IBM SPSS Regression includes:
- Multinomial logistic regression (MLR): Regress a categorical dependent variable with more than two categories on a set of independent variables. This procedure helps you accurately predict group membership within key groups.
You can also use stepwise functionality, including forward entry, backward elimination, forward stepwise or backward stepwise, to find the best predictor from dozens of possible predictors. If you have a large number of predictors, Score and Wald methods can help you more quickly reach results. You can access your model fit using Akaike information criterion (AIC) and Bayesian information criterion (BIC; also called Schwarz Bayesian criterion, or SBC).
- Binary logistic regression: Group people with respect to their predicted action. Use this procedure if you need to build models in which the dependent variable is dichotomous (for example, buy versus not buy, pay versus default, graduate versus not graduate). You can also use binary logistic regression to predict the probability of events such as solicitation responses or program participation.
With binary logistic regression, you can select variables using six types of stepwise methods, including forward (the procedure selects the strongest variables until there are no more significant predictors in the dataset) and backward (at each step, the procedure removes the least significant predictor in the dataset) methods. You can also set inclusion or exclusion criteria. The procedure produces a report telling you the action it took at each step to determine your variables.
- Nonlinear regression (NLR) and constrained nonlinear regression (CNLR): Estimate nonlinear equations. If you are you working with models that have nonlinear relationships, for example, if you are predicting coupon redemption as a function of time and number of coupons distributed, estimate nonlinear equations using one of two IBM SPSS Statistics procedures: nonlinear regression (NLR) for unconstrained problems and constrained nonlinear regression (CNLR) for both constrained and unconstrained problems.
NLR enables you to estimate models with arbitrary relationships between independent and dependent variables using iterative estimation algorithms, while CNLR enables you to:
- Use linear and nonlinear constraints on any combination of parameters
- Estimate parameters by minimizing any smooth loss function (objective function)
- Compute bootstrap estimates of parameter standard errors and correlations
- Weighted least squares (WLS): If the spread of residuals is not constant, the estimated standard errors will not be valid. Use Weighted Least Square to estimate the model instead (for example, when predicting stock values, stocks with higher shares values fluctuate more than low value shares.)
- Two-stage least squares (2LS): Use this technique to estimate your dependent variable when the independent variables are correlated with the regression error terms.
For example, a book club may want to model the amount they cross-sell to members using the amount that members spend on books as a predictor. However, money spent on other items is money not spent on books, so an increase in cross-sales corresponds to a decrease in book sales. Two-Stage Least-Squares Regression corrects for this error.
- Probit analysis: Probit analysis is most appropriate when you want to estimate the effects of one or more independent variables on a categorical dependent variable.
For example, you would use probit analysis to establish the relationship between the percentage taken off a product, and whether a customer will buy as the prices decreases. Then, for every percent taken off the price you can work out the probability that a consumer will buy the product.
- IBM SPSS Regression includes additional diagnostics for use when developing a classification table
IBM SPSS Custom Tables
IBM® SPSS® Custom Tables helps you easily understand your data and quickly summarize your results in different styles for different audiences.
More than a simple reporting tool, IBM SPSS Custom Tables combines comprehensive analytical capabilities with interactive table-building features to help you learn from your data and communicate the results of your analyses as professional-looking tables that are easy to read and interpret.
- Compare means or proportions for demographic groups, customer segments, time periods or other categorical variables when you include inferential statistics
- Select summary statistics - from simple counts for categorical variables to measures of dispersion - and sort categories by any summary statistic used
- Choose from three significance tests: Chi-square test of independence, comparison of column means (t test), or comparison of column proportions (z test)
- Drag and drop variables onto the interactive table builder to create results as pivot tables
- Preview tables in real time and modify them as you create them
- Exclude specific categories, display missing value cells and add subtotals to your tables

IBM SPSS Data Preparation Overview, Features, and Benefits
IBM® SPSS® Data Preparation gives analysts advanced techniques to streamline the data preparation stage of the analytical process. All researchers have to prepare their data before analysis. While basic data preparation tools are included in IBM SPSS Statistics Base, IBM SPSS Data Preparation provides specialized techniques to prepare your data for more accurate analyses and results.
With IBM SPSS Data Preparation, you can:
- Quickly identify suspicious or invalid cases, variables and data values
- View patterns of missing data
- Summarize variable distributions
- Optimally bin nominal data
- More accurately prepare your data for analysis
- Use Automated Data Preparation (ADP) to detect and correct quality errors and impute missing values in one efficient step
- Get recommendations and visualizations to help you determine which data to use
Expand your Data Preparation Techniques with IBM SPSS Data Preparation
Perform Data Checks
Data validation has typically been a manual process. You might run a frequency on your data, print the frequencies, circle what needs to be fixed and check for case IDs. This approach is time consuming and prone to errors. And since every analyst in your organization could use a slightly different method, maintaining consistency from project to project may be a challenge.
To eliminate manual checks, use the IBM SPSS Data Preparation Validate Data procedure. This enables you to apply rules to perform data checks based on each variable's measure level (whether categorical or continuous).
For example, if you're analyzing data that has variables on a five-point Likert scale, use the Validate Data procedure to apply a rule for five-point scales and flag all cases that have values outside of the 1-5 range. You can receive reports of invalid cases as well as summaries of rule violations and the number of cases affected. You can specify validation rules for individual variables (such as range checks) and cross-variable checks (for example, "retired 30 year-olds").
With this knowledge you can determine data validity and remove or correct suspicious cases at your discretion before analysis.
Quickly Find Multivariate Outliers
Prevent outliers from skewing analyses when you use the IBM SPSS Data Preparation Anomaly Detection procedure. This searches for unusual cases based upon deviations from similar cases, and gives reasons for such deviations. You can flag outliers by creating a new variable. Once you have identified unusual cases, you can further examine them and determine if they should be included in your analyses.
Pre-process Data before Model Building
In order to use algorithms that are designed for nominal attributes (such as Naïve Bayes and logit models), you must bin your scale variables before model building. If scale variables aren't binned, algorithms such as multinomial logistic regression will take an extremely long time to process or they might not converge. This is especially true if you have a large dataset. In addition, the results you receive may be difficult to read or interpret.
IBM SPSS Data Preparation Optimal Binning, however, enables you to determine cutpoints to help you reach the best possible outcome for algorithms designed for nominal attributes.
With this procedure, you can select from three types of binning for pre processing data:
- Unsupervised -- create bins with equal counts
- Supervised -- take the target variable into account to determine cutpoints. This method is more accurate than unsupervised; however, it is also more computationally intensive.
- Hybrid approach -- combines the unsupervised and supervised approaches. This method is particularly useful if you have a large number of distinct values.
IBM SPSS Missing Values
IBM® SPSS® Missing Values is used by survey researchers, social scientists, data miners, market researchers and others to validate data.
Missing data can seriously affect your models – and your results. Ignoring missing data, or assuming that excluding missing data is sufficient, risks reaching invalid and insignificant results. To ensure that you take missing values into account, make IBM SPSS Missing Values part of your data management and preparation.
Uncover Missing Data Patterns

Uncover Missing Data Patterns
With IBM SPSS Missing Values, you can easily examine data from several different angles using one of six diagnostic reports to uncover missing data patterns. You can then estimate summary statistics and impute missing values through regression or expectation maximization algorithms (EM algorithms).
IBM SPSS Missing Values helps you to:
- Diagnose if you have a serious missing data imputation problem
- Replace missing values with estimates -- for example, impute your missing data with the regression or EM algorithms
Quickly and Easily Diagnose Your Missing Data
Reach More Valid Conclusions
Use Multiple Imputation to Replace Missing Data Values
IBM SPSS Missing Values' multiple imputation procedure will help you understand patterns of “missingness” in your dataset and enable you to replace missing values with plausible estimates. It offers a fully automatic imputation mode that chooses the most suitable imputation method based on characteristics of your data, while also allowing you to customize your imputation model.
Several complete datasets are generated (typically, three to five), each with a different set of replacement values. Next, you can model the individual datasets, using techniques such as linear regression, to produce parameter estimates for each dataset. Then you can obtain final parameter estimates. This involves pooling the individual sets of parameter estimates obtained in step two and computing inferential statistics that take into account variation within and between imputations.
Analysis of the individual datasets and pooling of the results are supported via existing IBM SPSS Statistics procedures such as REGRESSION. When operating on datasets with imputed values, existing procedures will automatically produce pooled parameter estimates.
Fill in the Blanks for Improved Data Management
IBM SPSS Missing Values has the statistics you need to fill in missing data:
- Univariate: compute count, mean, standard deviation, and standard error of mean for all cases excluding those containing missing values, count and percent of missing values, and extreme values for all variables
- Listwise: compute mean, covariance matrix, and correlation matrix for all quantitative variables for cases excluding missing values
- Pairwise: compute frequency, mean, variance, covariance matrix, and correlation matrix
- Expectation maximization (EM) algorithm
- Estimate the means, covariance matrix, and correlation matrix of quantitative variables with missing values, assuming normal distribution, t distribution with degrees of freedom, or a mixed-normal distribution with any mixture proportion and any standard deviation ratio
- Impute missing data and save the completed data as a file
- Regression algorithm
- Estimate the means, covariance matrix, and correlation matrix of variables set as dependent; set number of predictor variables; set random elements as normal, t, residuals, or none
IBM SPSS Missing Values also has features that enable you to analyze patterns and manage data, including the ability to:
- Display missing data and extreme cases for all cases and all variables using the data patterns table
- Determine differences between missing and non-missing groups for a related variable with the separate t test table
- Assess how much missing data for one variable relates to the missing data of another variable using the percent mismatch of patterns table

IBM SPSS Conjoint
IBM® SPSS® Conjoint gives you a realistic way to measure how individual product attributes affect people’s preferences.
When you use both conjoint analysis and competitive product market research for your new products, you are less likely to overlook product dimensions that are important to your customers or constituents, and more likely to successfully meet their needs.
With IBM SPSS Conjoint, you can easily measure the tradeoff effect of each product attribute in the context of a set of product attributes – as consumers do when making purchasing decisions.
For example, you can answer critical product market research questions:
- What product attributes do my customers care about?
- What are the most preferred attribute levels?
- How can I most effectively perform pricing and brand equity studies?
You can answer all of your questions before you spend valuable resources trying to bring products or services to market. Use IBM SPSS Conjoint to focus your efforts on the service or product development that has the best chance of succeeding.
IBM SPSS Conjoint gives you all the tools you need for developing product and service attribute ratings. You can use its three procedures to:
- Generate designs easily – use Orthoplan, the design generator, to produce an orthogonal array of alternative potential products or services that combine different product/service features at specified levels
- Print "cards" to elicit respondents' preferences – use Plancards to quickly generate cards that respondents can sort to rank alternative products
- Get informative results – analyze your data using Conjoint, a procedure that's a specially tailored version of regression. Find out which product/service attributes are important and at which levels they are most preferred. You can also perform simulations that tell you the market share of preference for alternative products
Conduct intelligent planning
Expand the capabilities of IBM SPSS Statistics Base with IBM SPSS Conjoint. Make better decisions about your data and gain knowledge in the planning stage that you can carry throughout the analytical process.
Save time and money by generating a set of conjoint experimental trials that are a fraction of all possible combinations and attribute levels. You'll quickly learn how your respondents rank their preferences when you create and print cards they can sort. And, with the results from the Conjoint procedure, you'll learn how your respondents rank product attributes. Here are more details on each procedure:
- Orthoplan enables you to generate orthogonal main effects fractional factorial designs and display results in pivot tables.
- Plancards enables you to produce printed cards for a conjoint experiment.
- Conjoint enables you to perform an ordinary least-squares analysis of preference or rating, working with a plan file generated through Plancards or with one inputted from a data list. Various graphing and printing options are available.

Use data mining techniques
IBM SPSS Neural Networks provides a complementary approach to the data analysis techniques available in IBM SPSS Statistics Base and its modules. From the familiar IBM SPSS Statistics interface, you can “mine” your data for hidden relationships, using either the Multilayer Perceptron (MLP) or Radial Basis Function (RBF) procedure.
Both of these are supervised learning techniques – that is, they map relationships implied by the data. Both use feed-forward architectures, meaning that data moves in only one direction, from the input nodes through the hidden layer or layers of nodes to the output nodes.
Your choice of procedure will be influenced by the type of data you have and the level of complexity you seek to uncover. While the MLP procedure can find more complex relationships, the RBF procedure is generally faster.
With either of these approaches, the procedure operates on a training set of data and then applies that knowledge to the entire dataset, and to any new data.
Control the process from start to finish
Graphically display underlying relationships
IBM SPSS Categories’ dimension reduction techniques enable you to clarify relationships in your data by using perceptual maps and biplots:
- Perceptual maps are high-resolution summary charts that graphically display similar variables or categories close to each other. They provide you with unique insight into relationships between more than two categorical variables.
- Biplots and triplots enable you to look at the relationships among cases, variables and categories. For example, you can define relationships between products, customers and demographic characteristics.
By using the preference scaling feature, you can further visualize relationships among objects. The breakthrough algorithm on which this procedure is based enables you to perform non-metric analyses for ordinal data and obtain meaningful results. The proximities scaling procedure allows you to analyze similarities between objects, and incorporate characteristics for objects in the same analysis.
The data are a 2x5x6 table containing information on two genders, five age groups and six products. This plot shows the results of a two-dimensional multiple correspondence analysis of the table. Notice that products such as "A" and "B" are chosen at younger ages and by males, while products such as "G" and "C" are preferred at older ages.

Turn qualitative variables into quantitative ones
Perform additional statistical operations on categorical data with the advanced procedures available in IBM SPSS Categories:
- Use optimal scaling procedures to assign units of measurement and zero-points to your categorical data
- Choose from state-of-the art procedures for model selection and regularization
- Perform correspondence and multiple correspondence analyses to numerically evaluate similarities between two or more nominal variables in your dataset
- Summarize your data according to important components by using principal components analysis
- Quantify your ordinal and nominal variables with an optimal scaling correlation matrix
- Use nonlinear canonical correlation analysis to incorporate and analyze variables of different measurement levels
Procedures and statistics for analyzing categorical data
Using IBM SPSS Categories with IBM SPSS Statistics Base gives you a selection of statistical techniques for analyzing high-dimensional or categorical data, including:
- Categorical regression that predicts the values of a nominal, ordinal or numerical outcome variable from a combination of categorical predictor variables. Optimal scaling techniques are used to quantify variables. Three regularization methods: Ridge regression, the Lasso and the Elastic Net, improve prediction accuracy by stabilizing the parameter estimates.
- Correspondence analysis that enables you to analyze two-way tables that contain some measurement of correspondence between rows and columns, as well as display rows and columns as points in a map.
- Multiple correspondence analysis which is used to analyze multivariate categorical data by allowing the use of more than two variables in your analysis. With this procedure, all the variables are analyzed at the nominal level (unordered categories).
- Categorical principal components analysis uses optimal scaling to generalize the principal components analysis procedure so that it can accommodate variables of mixed measurement levels.
- Nonlinear canonical correlation analysis uses optimal scaling to generalize the canonical correlation analysis procedure so that it can accommodate variables of mixed measurement levels. This type of analysis enables you to compare multiple sets of variables to one another in the same graph, after removing the correlation within sets.
- Multidimensional scaling performs multidimensional scaling of one or more matrices with similarities or dissimilarities (proximities).
- Preference scaling visually examines relationships between two sets of objects, for example, consumers and products. Preference scaling performs multidimensional unfolding in order to find a map that represents the relationships between these two sets of objects as distances between two sets of points
