Description

Computes typicality tests for a list of supplementary variables of a MCA.

Usage

dimtypicality(resmca, vars, dim = c(1,2), max.pval = 1)

Value

Returns a list of data frames giving the typicality test statistics and p-values of the supplementary categories for the different axes.

Arguments

resmca

object of class MCA, speMCA, csMCA, stMCA or multiMCA

vars

a data frame of supplementary variables

dim

the axes for which typicality tests are computed. Default is c(1,2)
