PLS Predict Negative Results
Posted: Thu Nov 15, 2018 2:39 pm
Hi PLS experts,
I run my model using PLS Predict. I have three main variables in my study. The PLS output in the LV Prediction Summary-PLS table, RMSE and MAE columns indicate positive values for all variables. As for Q2 column, two variables are of positive values while the remaining variable is negative (i.e. -0.072).
My question, is it common for having negative value in PLS Predict? How to interpret the negative value?
Thanks~
