Description Details Author(s) References See Also
This package performs a homogeneity analysis and various extensions. Rank restrictions on the category quantifications can be imposed (nonlinear PCA). The categories are transformed by means of optimal scaling with options for nominal, ordinal, and numerical scale levels (for rank-1 restrictions). Variables can be grouped into sets, in order to emulate regression analysis and canonical correlation analysis.

The basic function of the homals package is homals(data)
which performs
homogeneity analysis and returns an object of class "homals"
. It allows for
grouping variables into sets, constraining ranks on category quantifications and levels.
Various plot functions are provided in plot.homals
and plot3d.homals
.
