All are planned features and are subject to change. Note: the Titles/sub-title feature for the Draft Viewer originally planned for this version 9.0 will not be included in this release. The PROXSCAL update originally planned for SPSS Categories 9.0.1 will now be in the 9.0.2 release.
Predict categorical outcomes with more than two categories with the Mu 11211m1224l ltinomial Logistic Regression in SPSS Regression Models (formerly named SPSS Professional Statistics). For example, model what predicts whether the customer buys product A, product B or product C.
PROXSCAL will be added to SPSS Categories 9.0.2. When you update to SPSS Categories 9.0, you will receive SPSS Categories 9.0.2 update at no additional cost, planned for delivery Q2, 1999. With PROXSCAL, find the "hidden structure" in the data by assigning observations to specific locations in "conceptual space. You can represent similarity and dissimilarity data in a low-dimensional space to gain 'spatial" understanding of how objects relate.
PROXSCAL is more reliable and stable than other MDS programs:
Convergence of stress is guaranteed
Avoids negative disparities that may arise when specifying an interval transformation
PROXSCAL is more flexible than other MDS programs. You can:
Impose external constraints on the MDS configuration
Allow for n-1 dimensions
General operations
Formatting capabilities for output
Transform a table into a graph for more visually compelling information.
Titles/sub-title feature for the Viewer
Create cleaner looking tables with box characters in Draft Viewer.
Keep a record of your work with the default of 'append' in journal files.
More intelligent placement of page breaks in Draft Viewer.
Graphing capabilities
Compare the frequency distributions of your continuous-level data using area graphs.
Easily compare groups with straightforward stacked bar graphs.
Visualize related variables or multiple responses side by on for example, a line graph.
Simultaneously show information on two different scales with secondary axis graphs (for example in US dollars and British pounds).
Focus on the data that interests you-specify data ranges in graphs at creation time through the UI.
Get a great combination of automation and interactivity with IGRAPH scripting support for use with SmartViewer Web Server and Developer's Kit.
Histograms and Scatterplots
Visually review residuals and identify outliers in regression lines, smoothers, centroids and means via spikes.
Attribute controls
Set benchmarks for data comparison in graphs with interactive reference lines
Clarify and highlight your graph as you re-order and hide categories.
Streamline presentation/publication graphics with performance enhancements in graph creation, printing times, creation dialogs
Usability improvements to Histogram, 3D axis effect, text editing, labeling in panels, keys, errors and warnings.
Statistics
Make more informed decisions by evaluating the diagnostic performance of a test
Get a clear visual and quantitative report of the test's accuracy and estimated error.
Select decision thresholds
Go beyond the limits of a two-way crosstab as you explore three-way relationships in categorical data with Cochran-Mantel-Haenszel statistic in Crosstabs.
Better understand your data's segmentation with better looking dendogram in Cluster.
Find the hidden structure in your similarity data using ALSCAL Multidimensional Scaling.
Matrix operations
Write your own statistical routines in the compact language of matrix algebra.
Data management
Identify and select variables using your own organization scheme as you sort variables according to variable labels in list box
File management
Easily read in and define ASCII data with the Text Wizard like Excel's.
Leverage your existing data from Oracle Express, Hyperion Essbase and Business Objects via direct data interfaces.
Insure you have read in the right file with a quick summary of your data file
Increase the accuracy and repeatability of your syntax files with Search & replace enhancements.
Transformations
Get a clearer understanding of your continuous data's distribution as you automatically divide variables into categories via NTILES, and create new variable(s) for each category.
