does multinomial logistic model from multinom (nnet) has logLik?
I want to get the logLik to calculate McFadden.R2 ,ML.R2 and
Cragg.Uhler.R2, but the value from multinom does not have logLik.So my
quetion is : is logLik meaningful to multinomial logistic model from
multinom?If it does, how can I get it?
Thank you!
ps: I konw VGAM has function to get the multinomial logistic model
with logLik, but I prefer use the function...

The first column represents r^2 values obtained by linear regression
models, then comes McFadden pseudo r^2, maximum likelihood pseudo r^2, and
Cragg and Uhler's pseudo r^2.
As far as I understand, Cragg and Uhler's pseudo r^2 is similar to
Nagelkerke, which, in contrast to the other pseudo r^2 values, offers a
range between 0 and 1, so that should be my comparison. And the values are
between 3 and 7 times higher than the original r-squ...
