Hello, I am not quite sure how to get Cox-Snell and Naglekerke R-square values in logistic regression. Please advise. Thank you.
In the Testing Global Null Hypothesis: BETA=0 output table , "RSquare" is Cox and Snell R2 and "Max-rescaled RSquare" is Nagelkerke R2
Specify the RSQUARE option in the MODEL statement of PROC LOGISTIC to get both.
