Does anybody know where can I find R/Splus code for computing
PREdiction Sum of Squares (PRESS)
in a linear regression model?
I have a large regression model (~100 predictors, ~30,000 cases)
and good prediction is the main goal.
I remember there is a faster way to compute it (no need to
repeatedly fit models), but if there is existing code......
