The variance of the inverse binomial estimator
C.S.I.R.O. North Ryde, New South Wales
A closed form for the variance of the unbiased estimator of the proportion defective in a population, derived by inverse binomial sampling, is given. Comparisons are made with the maximum likelihood estimator which indicate that the unbiased estimator has greater efficiency and smaller mean squared error.
