Ergebnisse vorhersagen und Beziehungen in kategorischen Daten aufdecken
IBM SPSS Categories liefert Ihnen sämtliche Hilfsmittel, die Sie benötigen, um einen klaren Einblick in komplexe kategorische und numerische sowie hochdimensionale Daten zu gewinnen.
Setzen Sie IBM SPSS Categories ein, um zu verstehen, welche Merkmale die Verbraucher am stärksten mit Ihrer Marke verbinden, oder um zu ermitteln, wie die Kunden Ihre Produkte im Vergleich zu anderen Produkten wahrnehmen, die Sie oder Ihre Mitbewerber anbieten.
- Entdecken Sie die zugrundeliegenden Beziehungen über Wahrnehmungskarten, Bi-Plots und Tri-Plots
- Verstehen Sie und arbeiten Sie mit Nominaldaten (z. B. Gebiete) und Ordinaldaten (z. B. Ausbildungsniveau) mithilfe von Prozeduren, die der konventionellen Regression, den Hauptkomponenten und der kanonischen Korrelation ähneln, um Ergebnisse zu prognostizieren und Beziehungen offenzulegen
- Interpretieren Sie Datenbestände visuell und sehen Sie sich an, wie Zeilen und Spalten in großen Tabellen mit Punktzahlen, Zählerständen, Bewertungen, Ranglisten oder Ähnlichkeiten zusammenhängen
- Arbeiten Sie mit nicht normalen Residuen in numerischen Daten oder nicht linearen Beziehungen zwischen Voraussagevariablen (z. B. Kunden- oder Produktattribute) und Ergebnisvariablen (z. B. eingekauft/nicht eingekauft)
- Verwenden von Ridge-Regression, Lasso, Elastic Net, Variablenauswahl und Modellauswahl sowohl für numerische als auch für kategoriale Daten
- Unterstützte Betriebssysteme: Windows, Mac, Linux

Unleash the full potential of your data through predictive analysis, statistical learning, perceptual mapping, preference scaling and dimension reduction techniques – including optimal scaling of your variables.
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.
