Does it make sense to calculate Q2 and R2 values on PLS-DA …
The R2 and Q2 are calculated using the labels in numerical form (-1 and 1 or 0 and 1 instead of green and yellow).

What is difference between “in-sample” and “out-of-sample” …
Suppose in your sample, you have a sequence of 10 data points. This data can be divided into two parts - e.g. first 7 data points for estimating the model parameters and next 3 data points to test the model performance.
Is this a common formula to find pseudo R-squared for this GLM?
I'm trying to figure out if this common pseudo R-squared formula is acceptable for the GLM I am running. Here is the code and formula: m1<- glm((AdjustedActivity3+1)~HDtype, family = Gamma(link...
regression - Higher $r^2$ value on test data than training data ...
One explanation might relate to how you subset your test data (they way you split training and testing data). If your test data only consists of (just a few) similar observations then it is very likely for your R-squared measure to be different than that of the training da
Should $ R^2$ be calculated on training data or test data?
