|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
phi.data.frame. These functions are built from corresponding functions of the package
cramer.folder(xf) tschuprow.folder(xf) pearson.folder(xf) phi.folder(xf)
an object of class
A list the length of which is equal to the number of data frames of the folder. Each element of the list is a square matrice giving the pairwise association measures of the variables of the corresponding data frame.
