PCA analysis on data with different scales

Post by jan.zachar »

I would like to ask what is the best practice to preform PCA analysis on data (variables) with different scales (e.g. environmental measurements). As far as I remember the PAST soft enables to normalize data "on the fly" by choosing "correlation" option instead of "variance -co-variance" by launching the PCA.

Thank you

Jan
