Dear all, This is my maidenpost (I am a new member since 5 minutes) to this list. My problem is the following: I have a dataset with morphometric data from fishes (33 measurements per fish; 11 males and 10 females per sample location; 3 different sample locations; 2 different fish species).
I want to perform a PCA on these data, but I am wondering wether I should use the real data (log transformed) or wether I should use the residuals for the PCAnalysis? (After having done the PCA, I want to select the most contributing variables through a Factor Analysis; then I will do an ANOVA on each of the selected variables to investigate which samples are different from each other) Kind regards, Dieter Anseeuw [EMAIL PROTECTED]
