DESCRIPTION

Varimax rotation is a change of coordinates used in principal component analysis and factor analysis that maximizes the sum of the variances of the squared loadings matrix. This module exports a single routine 'rotate'. This routine is called in LIST context and accepts a LIST-of-LISTS (LoL) corresponding to the loadings matrix of a factor analysis and returns two references to LoLs. The first is a LoL of the rotated loadings and the seconds is a LoL of the orthogonal matrix. See http://en.wikipedia.org/wiki/Varimax_rotation.
