A Two-Stage Adaptive Group-Testing Procedure for Estimating Small Proportions
估计小比例的两阶段自适应群组检测程序
A method for adaptively estimating a proportion p using group-testing procedures is presented and analyzed, with emphasis placed on a two-stage procedure. This estimator is compared to the usual group-testing estimator via asymptotic and small-sample relative efficiency. The adaptive estimator is generally recommended with the restriction that adaptations (i.e., adjustments of group size) are based on at least 10 measurements/responses. But if one is confident that one has a…
