The Data Viewer provides a convenient interface for looking at the statistical properties of any StatTools data set using graphs and tables.
The Cluster Analysis command searches for patterns in a data set in order to classify observations or variables into groups of similar items.
Principal Component Analysis
The Principal Component Analysis is a procedure for analyzing multivariate data; it transforms a set of correlated variables into a smaller set of uncorrelated variables.
Bar Chart Graphs
The Bar Chart command creates multiple bar charts representing each selected variable, or a single bar chart for all the selected variables.
The Kruskal-Wallis Test command performs a nonparametric hypothesis test on three or more samples.
New Regression Features
- Support for different regression models, including Dummy Variable Regression, Polynomial Regression, Regression with Interactions between Variables, Regression with Nonlinear Variable Transformations.
- Wizard to support building standard regression models.
- Flexible interface for building a custom model, including category variables and transformations of numeric variables ("derived variables").
- Option to "Fix Independent Variables": select independent variables that will never be excluded from the equation during the variable selection process.
- Significant improvement to the speed of the regression analysis.
Other Changes of Note
Improved Support for High-DPI Monitors: High-resolution monitors require special Windows settings that scale up the size of text and some elements of dialogs; otherwise, those items would be too small. Compatibility with this setup has been improved.
Supported Excel Versions: Requires Excel 2007 or Higher StatTools now requires Excel 2007 or higher. Excel 2003, or earlier versions, are no longer supported.
A Selection of Significant Maintenance Fixes:
11064 Protected Workbook dialog sometimes is displayed behind Excel 2013.
11151 Error creating a Box-Whisker plot for a very large data set.
11206 Issue with missing data handling in Hypothesis Test for mean difference.
11390 The “pipe symbol” list separator ‘|’ prevents StatTools from running properly. StatTools will now check this when the product launches.
11603 Some Data Utilities slow with very large data sets; improved performance for Lag, Difference, Transform, and Interaction utilities.
