This update includes our proprietary MARS®  Regression feature which expands upon Minitab’s predictive analytics capabilities to create accurate predictive models for a continuous response with many continuous and categorical predictor variables. Minitab 21.4 also includes graph editing enhancements and the ability to update or create new results for some statistical features when data change.

New Feature: Multivariate Adaptive Regression Splines (MARS)

User Benefit

MARS® is an important alternative analytical technique when conventional regression methods fail to work.

Summary

MARS® is our latest advanced predictive analytics solution that uncovers important data patterns and relationships that are difficult, if not impossible, for other regression methods to reveal. The MARS modeling engine builds its model by piecing together a series of straight lines, with each allowed its own slope. This permits the MARS modeling engine to trace out any pattern detected in the data.

New Feature: Interactive Graph Editing

  • Add Regression Fit for Scatterplot & Matrix Plot
  • Add Percentile Line for Probability Plot 
  • Adjust Probability Plot Y-Scale
  • Adjust Histogram Binning

User Benefit

This graph editing feature update allows users to customize their results.

Summary

  • Add Regression Fit for Scatterplot & Matrix Plot
    This feature provides the option to add a regression fit to an already-created scatterplot or matrix plot via the editing pane and specify the type as well as whether to include the y-intercept.

  • Add Percentile Line for Probability Plot
    This feature provides the option to add percentile lines at specified values along the X or Y scale to an already-created probability plot. Note: this option will apply to the selected graph only.

  • Adjust Probability Plot Y-Scale
    This feature will provide the option to change the Y-scale type between percent, probability, and score on an already-created probability plot. Note: this option will apply to the selected graph only.

  • Adjust Histogram Binning
    This feature provides the option to change the interval type on the X-scale (binning) between midpoint and cutpoint as well as the interval definition for binning by specifying the number of intervals or choosing custom midpoint/cutpoint positions on a histogram. Note: this option will apply to the selected graph only.
