dimtypicality: Typicality tests for supplementary variables of a MCA

Description Usage Arguments Value Author(s) References See Also Examples

View source: R/dimtypicality.R

Description

Computes typicality tests for a list of supplementary variables. It allows to analyze variants of MCA, such as 'specific' MCA or 'class specific' MCA.

Usage

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

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)

max.pval

only categories with a p-value lower or equal to max.pval are displayed. By default, all categories are displayed

Value

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