Thank you Peter for showing me the error. I did not realize it. Now I have removed that cohort (there was just one observation!) and checked the numbers for each of the other cohorts. I have re-run the model and now it seems to make much more sense to me. I am going to use one specific cohort,

Hi all, I can't find the error in the binomial GLM I have done. I want to use that because there are more than one explanatory variables (all categorical) and a binary response variable. This is how my data set looks like: str(data) 'data.frame': 1004 obs. of 5 variables: $ site : int 0 0

1. As this is a statistical, rather than an R issue, you would do better posting on a statistical help site like stats.stackexchange.com (although some generous soul here may respond). 2. You would also probably do better consulting with a local statistical resource if available, as it is

Perhaps I haven't explained it that well as I would have liked to. To me this was an R issue because I didn't understand why the binomial GLM is getting these results and I believed this was something due to the way I am implementing it in R, not to the binomial GLM itself. If I was wrong and
