Visualizing Hypothesis Tests in Multivariate Linear Models
Description
Provides HE plot and other functions for visualizing hypothesis
tests in multivariate linear models. HE plots represent sums-of-squares-and-products
matrices for linear hypotheses and for error using ellipses (in two
dimensions) and ellipsoids (in three dimensions). It also provides other tools for analysis and graphical display of the models
such as robust methods and homogeneity of variance covariance matrices.
The related 'candisc' package provides visualizations in a reduced-rank canonical discriminant space when
there are more than a few response variables.
