1. How to get PRESS values in JMP when using PLS2 NIPALS and Leave out One data ?
2. When finding RMS PRESS using hand written code I get matching answers for toy problems using (n-1)*k as averaging factor where n is no. of observations and y is number of responses.
3. But in large problems like Baltic or Gasoline the RMS PRESS was not matching with handwritten code. But coefficients of the model are matching exactly.
So I require PRESS values and approach followed in JMP for finding RMS PRESS.
Thank you
