[Basta-users] Perfect detection problem

[Tschirren, Barbara]

Dear BaSTA Team,
I tried to estimate age-specific survival in my system but continued to get the error message
Calculating DIC...Error in rep(0, nbd) : invalid 'times' argument
My system has a 100% detection probability and 100% of the birth dates are known.  I started to suspect that this might cause the problem. Indeed, when randomly adding some observation uncertainty (i.e. replacing a single known birth date with 0) the simulations ran smoothly. Is there a way to get around this problem, e.g. by specifying very strong priors?
Many thanks for your help,
Barbara
