association measures for folder | R Documentation |
Computes the pairwise association measures (Cramer's V, Pearson's contingency coefficient, phi, Tschuprow's T) between the categorical variables of an object of class folder
. The computation is carried out using the functions cramer.data.frame
, tschuprow.data.frame
, pearson.data.frame
or phi.data.frame
. These functions are built from corresponding functions of the package DescTools
(see Assocs
)
