R2 function from PLS to use a model on test data
...actors, ncomp=10 data=MiceTrain)
R2(mice1) ##this provides the correct R2 for the Train data for 10
components
## Now my next objective is to calculate my model's R2 for each component on
the Test data. (In other words - test how good the model is on test data)
The only thing I need are the MiceTest.response, and compare that with
predict(mice1, ncomp=1, newdata=MiceTest , and I should be able to calculate
R2.....but I can't figure out the correct command to do this. I tried the
command below, which does provide a different R2 response, however, I'm not
sure it is correct as I get a...
