Hello,
After using the POPAN formulation, I got the following gross population estimates for my study population. I want to estimate population size at the end of the sample period. Let's say I got the following summary.
To get the population size I added the N*-hat from group 1 to 6. But what about the confidence intervals? How can I calculate that? Any help is appreciated.
95% Confidence Interval
Grp. Occ. N*-hat Standard Error Lower Upper
