I've done it after bootstrapping eigen coefficients so that I have some confidence in a rejection of isometry when dealing with multiple groups (Common PCAs). I've got an unpublished manuscript (revising it now actually) explaining my methods if you would like to see it. But, you can probably also get the methods from some of C. Klingenberg's published papers and chapters. My email: [EMAIL PROTECTED]
