...trictions on the row and column scores (they can be restricted to be in the span of a number of covariates). Thus the program can also do CCA (and more, because column scores can be restricted as well). I adapted the canonical partition of chi-square to restricted CA, and generalized the notion of Benzecri distances that are approximated from below. Row-wise and column-wise partitionings of the inertias are also printed. The CA program can make row plots, column plots, joint plots, regression plots, transformation plots, and Benzecri plots. It allows for four different scalings: x in the centroid o...

...A bit of exploration in the MASS source shows (12th line of the mca function body) : fs <- X.svd$u[, sec]/rep(p*X.svd$d[sec], c(n,n)) Shouldn't that be fs <- X.svd$u[, sec]/rep(p*X.svd$d[sec], rep(n,nf)) that gives the expected result ? Oh, BTW : Is mca identical or analogous to Benzecri's "analyse des correspondances" (analysis of a chi-squared distance table), or is this yet another analysis ?
