Details to factor analysis
I've been hoping someone else would reply. My only suggestion is: look up the formula for the quantities you want and calculate them directly, using matrix or vector arithmetic at the R command line. That's what most people do. - tom blackwell - u michigan medical school - ann arbor -

Well, it is no problem to use R or S-Plus for a principle component analysis (PCA). The function "princomp" works very well with my polychoric correlation matrix, that I use for this approach on ordinal variables. But I want to inspect the Kaiser-Meyer-Olkin-crieterion with the "measure of sampling adequancy (MSA)" and the anti-image-correlation matrix. I can't find any possibility to compute this. Please give me a hint. Many Thanks! Tino
