Hi,
Probably a ridiculously simple question I know, but how do I interpret the output to the
cross validation (the delta values) in relation to the relogit output? I assume I need to
compare it to the MSE from the original model. I know how to calculate MSE, and I see the
qi$ev predicted probabilties, but what do I compare this to? Do I need to calculate
observed probabilities through a standard glm model, compute MSE between that and qi$ev,
then look at the % difference between MSE from original and the delta values?
I've also tried calculating the sum of squares of the residuals (from z.out) and
dividing that by the degrees of freedom but this seems very low compared to the delta
values.
Thanks
