Hello,

The function 'PrincipalComponents' returns the the first principal
components vector of a group of input vectors.

Question 1.) Is it possible to define Method->"covariance" or is
correlation the only PC technique available?

Question 2.) How can I generate an inverse PC transform from my
PrincipalComponents output?


Thanks,


Peter
