Dear All,
I am using the function vuong of the package pscl to compare 2 non nested glm
models with a numeric response.
I did the following
m1<-glm(y ~x ,data=xxx)
m2<-glm(y ~z , data=xxx)
When calling the vuong function I get the following message:
> vuong(m1,m2)
Error in predprob.glm(m1) : your object of class glm is unsupported by
predprob.glmyour object of class lm is unsupported by predprob.glm
My guess is that this function does not support numeric response!!!!! How can I
solve the problem?
Any help will be really appreciated.
