New Features in SAS/INSIGHT ® in Version 7

There are significant new features in Version 7 SAS/INSIGHT. These include new statistical analyses and enhancements to the graphics. INSIGHT now supports several multivariate statistical techniques including principal component rotation analysis, canonical correlation analysis, maximum redundancy analysis, and canonical discriminant analysis, and it also supports comparison of means. There are also new robust measures of scale and tests for normality for univariate data as well as tests for differences of means across groups. New graphical enhancements include 3D surface plots, contour plots, 3D response surfaces, comparison of means circles in the box plots, and color blending of up to 5 colors. Several methods for surface fitting are provided including linear interpolation, thin-plate spline, kernel estimation, and using a parametric model
