Robust Estimators for Quantal Bioassay
二元反应生物测定的稳健估计量
Extensions of robust estimators for the location of a symmetric distribution are given for the quantal bioassay problem. Asymptotic properties of the estimators are derived. A comparison in terms of asymptotic efficiencies under different tolerance distributions is made between the Spearman-Karber estimator and the trimmed mean and Tukey biweight estimators.
