Hi everyone !
Here's my situation: I have a dataset of 58 batches in line, and 213 columns corresponding to my parameters Xs (ex: Glucose at culture day 1, Glucose at culture day 2 etc...) . I have couple of data missing here and there depending on the X and the batches but on the overall the dataset is quite fine.
Now I want to use PLS to put all my Xs and try to understand which of them impact my Y (I have 14 different Ys I would like to understand individually, so all the Xs versus one Y).
For some of the Ys, it works fine, but for some other, the RM PRESS Plot advises "Note: The minimum root mean PRESS is 1.25 and the minimizing number of factors is 0." and I cannot build any model therefore (for example Y_1 in the attached database).
Why is it doing that? I thought it might be linked to the missing data but then I do not understand why it would work for the other Ys?
