"Correlation" of variables to axes in MCA or mix analyses

Description

Represents the "correlation" of variables to axes in a MCA (from dudi.acm) or a mix analysis (from dudi.hillsmith or dudi.mix).

Usage

scat.cr(dudi.obj, axis = 1)

Arguments

Details

For quantitative variables, the squared correlation coefficient is displayed. For ordered factors, the squared multiple correlation coefficient is displayed. For unordered factors, the correlation ratio is displayed.
