It is meant to be a replacement for G-pack. It looks very similar on the
outside but is more compact and better organized on the inside. The
clustering is the same (de-bugged), the eckart-young (singular value)
decomposition factor analysis has been modernized (leaping from a 1965
fortran II algorithm of Horst to a 'modern' 1982 one which produces 'nicer'
scaled loadings), and correlation matrices are rescaled if necessary to
allow squared -multiple-correlations to be calculated as better indices of
'intensity'. Added is principal components of construct correlations with a
range of possible rotations. I'm open to suggestions about what else might
go in. At the moment I'm planning to talk about it in Seattle.
