Hello All,
I've searched for a similar question but I couldn't seem to find any so here it goes....
For my data, an analysis of small mammal populations, I have been using a robust design model in RMark. I have 6 primary periods with 3 secondary periods each. I had the covariates sex, species, and treatment levels. My adviser now wants to add age as a covariate. At first, I thought this would be straight forward but because small mammals mature quickly, I have individuals that start as a juvenile and are adults by a different primary period. Is there an easy( lol nothing easy but logical) way to add this to the robust design model? I saw in chapter 7 of a gentle introduction that it is normally done with a cjs model a specific order of the PIMS but the way my data was collected was for a robust design model. I would greatly appreciate any tips or ideas, thank you in advance.
