ON ESTIMATING THE SIZE OF A POPULATION AND ITS INVERSE BY CAPTURE MARK METHOD
P. K. Pathak · 2016
SUMMARY. The problem of estimating the size of a population and its inverse is considered here on the basis of several independent simple random (without replacement) samples selected from the population. New estimates of the population size and its reciprocal are given. The estimate of the reci procal of the population size is the unbiased minimum variance estimate. The estimate of the population size is unbiased and has minimum variance only if the total sample size is not less than the population size. Variance estimates of these estimates are also given.
