Hi all, I have the following problem:

I've built a GLMM and it showed that one of the three levels of a factor differed from the intercept. So I've used the multcomp package in order to perform a multiple comparison and find out if the other two levels differed between each other. The results now are showing that none of the three levels actually differed. So something must be wrong....

I'm using the glmm.ADMB package.

the script line was

By default, glht is doing adjusting the p-value for multiple comparisons. By default, they use a single-step estimator. The code you propose above is equivalent to:
