Reiden,

Unfortunately, logistic regression procedures only provide a pseudo
r-squared that should not be compared across models.  The pseudo r-squared
cannot be interpreted in the same way that an OLS r-squared is interpreted.

Subject: Multinomial logistic regression: r2 for two different sets of
variables

Hi

I'm running a multinomial logistic regression and I'd like to find out which
set of variable contributes more to the total R2 (i.e.: variables that were
assessed before entering school (1th set) and variables that were assessed
after a few months in school (2nd set)).
I can only think of running two seperat regression models and compare the
two R2, but I'm sure there must be a more elegant way of doing this. I would
appreciate your help a lot.

Thank you in advance and kind regards

Rieden
