The removal method for two and three samples.

摘要: SUMMARY Moran's remnoval method for estimating the size N of an animal population is discussed case two samples and a new confidence interval proposed. This found to be more satisfactory than usual when < 200. The effect variable catchability in on maximum likelihood estimate also considered. It that Rq variance are both fairly insensitive such variations. robustness demonstrated three samples. L. INTRODUCTION Coinsider closed population, i.e. which immigration, emigration, birth, death, etc. absent (or at least negligible period investigation). Let this suppose k consecutive random yi (i = 1, 2, * *, k) removed from population. If p(= 1 - q), probability capture sample, same each remains constant sample then joint function y, , y2 ,. Yk given by
