homals-package {homals} | R Documentation |
This package performs a homogeneity analysis, aka a multiple correspondence analysis, but with many additional options. Variables can be grouped into sets, in order to emulate regression analysis and canonical analysis. For each variable there are, in addition, rank constraints on the category quantifications (or transformations) and level constraints (which allows one to treat a variable as nominal, ordinal, or numerical).

and plot3d.homals
.
