Multivariate Transformations
Hello folks,
many multivariate anayses (e.g., structural equation modeling) require
multivariate normal distributions.
Real data, however, most often significantly depart from the multinormal
distribution. Some researchers (e.g., Yuan et al., 2000) have proposed a
multivariate transformation of the variables.
Can you tell me, if and how such a transformation can be handeled in R?
Thanks in

It depends on what you are after. I am by no means a wunderkind when
it comes to transformation, but in the package vegan type
?wisconsin
and that should give you a start, but if you know what
transformations you would like to preform then apply should do what
you need with whatever transformation you are trying to use.
