PLS-DA distance method determination

Hello dear DEVS,
I hope you are doing well and in good health. Please do help me with this doubt mentioned below.
I have performed the PLS-DA analysis on the data i have. And the plot for classification error rates is as shows. How do i select which type of distance method to use.

hi @DARKSage77

We cover this in our tutorials on our websites. Given the large discrepancy between overall and BER, your results suggest you have an unbalanced design

→ choose base on the BER results

Then choose the lowest error rate

→ max.dist (although all distances + BER seem to give similar results).



Thank you soo much for the reply.
