Warning message in glmmADMB

Dear R mixed model experts,

Can anyone one confirm me if I get a warning message using glmmADMB for the
significance tests of random effects by comparing models with LRTs? I'm
using glmmADMB version 0.8.0 in R (version 3.1.0) and getting the following
warning message:

"Warning message:
In anova.glmmadmb(m1, m2) :
  rearranging models in order of increasing complexity"

Just for your kind information, I found an explanation from Ben Bolker
where he says that the updated version will fix / clarify this problem (
https://stat.ethz.ch/pipermail/r-sig-mixed-models/2012q1/017920.html). Is
it the version that I'm using?

I'm using this glmmADMB model for my zeroinflated and poisson data. If it
is not the appropriate model because of this warning, could you please
suggest me an alternative model (e.g. MCMCglmm)?

If I asked something odd/silly for this group,  sorry for that and please
ignore it.

?Thanks in advance,

Moshi

Dear Moshi,

just rearrange the tested models (as it is stated in the warning), e.g.:

anova(m2,m1)

and the warning should go away. It's only that the warning informs you
about the changed order of the models listed by the anova-result with
the smaller model (less df) being listed first. It does not say anything
about an inappropriate test...

Kind regards, Ulf
