Hi all,
Windows XP
R 2.10.0
I am trying to generate predictions from a binomial mixed model using glmer.
the models is as follows:
mod.PN <- glmer(PN_out~ as.factor(intr3) + transcode + Yr + (Yr|ID)
family=binomial,data=partset, na.action=na.omit)
where PN_out is a two column binomial variable
I then used the code suggested by BErt Gunter to predict from lmer:
here I am interested in making from two new predicting two new observations
where I hold everything fixed other than the factor intr3
predPN <- model.matrix(terms(mod.PN),newDat) %*% fixef(mod.PN)
this seems to work fine and the I print the predictions
print(PredPN)
[1] [2]
2.358722 2.312340
However I am not certain what I am looking at here, my best guess is that
each of these could the odds (p/1-p). But I am not at all sure in my guess,
any insights would be appreciated
Best,
Spencer
