Dear Ben and other list members, - Is there any way to produce a Anova/deviance table for a model fitted with glmmADMB ? I used the Anova() function from the car library for glmer models, but it does not seem to work with glmmadmb (I'm using glmmADMB 0.7) and I would like only one p-value for each term and interaction and NOT one p-value for each level of the interaction.
Hmmm. car::Anova() should work now -- I had to add a model.frame() and a df.residual() method for glmmadmb objects. (The df.residual number may be a little dodgy -- I'm not sure I counted the parameters right - -- but I don't think it's actually used for much by default, cause you get Wald chi-square tests) The newest version of glmmADMB is 0.7.5.1 -- it may take a little while for r-forge to catch up, and I was having a few dependency issues. If you don't see it there in ~ 24 hours, drop me a line.
- I also tried to compare nested models via LRT using anova(model1,model2) for glmmADMB models but I didn't get any p-values, it produced NaN, although it apparently calculate the differences in likelihood. Where can this come from ?
This ought to have worked: perhaps you had the models in the wrong order?
- I tried to use the coefplot2 library (downloaded from http://www.math.mcmaster.ca/bolker/R/src/contrib) as showed on the glmmADMB home page ("getting started with glmmADMB"), but I couldn't use it and got this error message : unable to find an inherited method for function "coefplot2", for signature "glmmadmb". Is it normal ? It worked fine with glmer output.
Can you try getting it from r-forge? Again, if the problem persists let me know. Ben
Thanks for your help ! Thomas
