[R-sig-ME] Multiple comparisons and post hoc tests on glmmTMB model, with the multcomp package.

[Julian Gaviria Lopez]

Hi,


I have the next model:

zipoisson <- glmmTMB(Observations ~ CAP * Condition + (1|ID), data=mDATA, ziformula=~ CAP * Condition , family=poisson)

Which result is:
 Family: nbinom1  ( log )
Formula:          Observations ~ CAP * Condition + (1 | ID)
Zero inflation:                ~CAP * Condition
Data: mDATA
     AIC      BIC   logLik deviance df.resid
  4798.4   4979.5  -2365.2   4730.4     1486

Random effects:
Conditional model:
 Groups Name        Variance Std.Dev.
 ID     (Intercept) 0.003643 0.06036
Number of obs: 1520, groups:  ID, 19

Overdispersion parameter for nbinom1 family (): 0.681

Conditional model:

I want to apply the Multiple comparisons and post hoc tests proposed in:
https://cran.r-project.org/web/packages/glmmTMB/vignettes/model_evaluation.html#mumin
but it is not clear to me what stands for "components" and "period"


Thanks in advance for any input.
