Estimators with Prescribed Bound on the Variance for the Parameters in the Binomial and Poisson Distributions, Based on Two-Stage Sampling

The problem of unbiased estimation of the parameter θ in the binomial and Poisson distributions is considered. The variance of the estimate is required not to exceed a preassigned bound, B. For the ...
