> maybe you have no power to estimate these kinds of models, or you have to 
centre age. 
For this trait, I have more than 100000 data on 1600 individuals with an 
exhaustive pedegree. It is huge. Clearly, the number of individuals decrease 
decrease with age so I decided to analyse from to 15 years (data until 22 year 
old).

Yes, I have. The distribution is poisson without any doubt. I tried to log the 
data

like?

Models are runnings
