Getting AIC from lrm in Design package
I am trying to obtain the AICc after performing logistic regression
using the Design package. For simplicity, I'll talk about the AIC. I
tried building a model with lrm, and then calculating the AIC as
follows:
likelihood.ratio <-
unname(lrm(succeeded~var1+var2,data=scenario,x=T,y=T)$stats["Model
L.R."]) #Model likelihood ratio???
model.params <- 2 #Num params in my model

lattice
...e. the fitted quadratics, 2 per panel. Is
this because lattice is still beta? or the construccion of the panel
function is different in lattice?
I am using R 1.3 on Win98
Thanks for any help.
