Choice of test in R. Repeated measurements, binary response and missing data...

[HannahKarolina]

I have two treatments and one co-variate (affect the response variable but is also correlated with one of the treatments). Each replicate has been examined for the presence/absence of morphological characters at several time point but there are unfortunately a lot of missing data. What would be the best way of analyzing this data? GLMM? GEE?

Could it be treat as time to event data?

Hmmm...Because my data is repeated measures I think glmer would suit the data better. Or do you beg to differ? I guess I need to pick only one time-point to include in the time to event analysis or can I use all of my data (from all 4 time points)?
