Describes the test-values of a list of supplementary variables for the axes of MCA and variants of MCA
Computes test-values for a list of supplementary variables. It allows to analyze variants of MCA, such as 'specific' MCA or 'class specific' MCA.
object of class
a list of supplementary variables
a vector of names for the supplementary variables. The vector's length must be equal to
the axes for which eta2 are computed. Default is 1:ncp
Test-values are ordered and only those higher than 2.58 (or lower than -2.58) are kept.
Returns a list of data frames giving the test-values of the supplementary categories for the different axes.
