I cannot seem to get the aic or extractaic call to work with multinomial
logistic regression models.
Here is what I am doing:
library('Design')
lrm1<-lrm(r1~p1)
#where p1 is multinomial and r1 is binomial
library('MASS')
aic(lrm1)
Error in if (fam %in% c("gaussian", "Gamma", "inverse.gaussian")) p <- p +
:
argument is of length zero
also tried extract.aic and others to no avail
I was able to get aic to give what looked to be reasonable results with nnet
functions like multinom -- am i missing basic statistics knowledge here or
is there a problem with my code? thanks
