GLMM predictor variables
Wrong list -- Your question is not about R. Post on a statistics list like stats.stackexchange.com -- or better yet, consult a local statistician for guidance. Cheers, Bert

Hi all,
I have a quick question regarding predictor variables in a GLMM analysis, a
subject I am new to.
I am running a study investigating multi-modal communication in primates.
specifically, primate gestures that accompany vocalizations.
I have measured the call rate, call duration and peak frequency (response
variables) for 200 calls (100 accompanied by gestures, 100 without
gestures).
I would like to use the following predictor variables: 1) Call type, 2)
Presence of gesture, 3) Gesture type
Is it possible to use GESTURE TYPE here as a predictor variable? I am not
sure if it's appropriate since this will only be for 50% of the overall
the data (where calls are accompanied by gestures).
Any advice would be greatly appreciated.
