Hi, I'm not able to get information about the following question: is the variables standardization a default option in manova() (stats package)? Or if you want to compare variables with different units or scales and rather different variances, you have to previously standardize the variables ?
If you mean the response variables, manova() does not require equal variances and does not standardize.
