I am trying to model age variation in survival in a multievent model using E-Surge. I have three groups: marked as juvenile (g1, 1st-years), marked as subadult (g2, 2nd-years) and marked as adult (g3, >2nd-years). From the GOF test 3G.SR I found out that I have a transient problem, but only in the adult group. Therefore, I want to model survival for 4 groups: Juveniles, Subadults, Adults en Transients (i.e., transient adults). The adults resulting from matured individuals within the groups “marked as juvenile” and “marked as subadult” will be included in the “Adults” group. I made shortcuts for the four groups:
Juveniles: g(1).a(1)
Subadults: [g(1).a(2)&g(2).a(1)]
Adults: [g(1).a(3)&g(2).a(2:3)&g(3).a(2:3)]
Transients: g(3).a(1)
In GEMACO, I defined for the survival part:
Juveniles+Subadults+Adults+Transients
When I try to run GEMACO, I get an “undetermined error in GEMACO”. What could be the problem here?
