I have three years of data with three surveys each year. I am trying to run a multi-season model. However, in 3 of the surveys (2 the first year and 1 the third year) there were no detections. So three of my columns in the presence/absence sheet are all zeros. I am still having some problems with convergence and am getting some standard errors equal to zero or very large standard errors.
My question is, is it a problem to have surveys with no detections and could this be the cause of myconvergence issues and poor standard error estimates?
Thanks for your assistance.
