Some Properties of Spearman-Type Estimators of the Variance and Percentiles in Bioassay
生物测定中 Spearman 型方差与百分位数估计量的性质
Theoretical results for the Spearman-type variance estimator in the quantal response bioassay problem are determined when the mean of the underlying tolerance distribution is known, and also when it is unknown. For an experiment with infinitely many dose levels, the estimator is proved to be finite with probability one, and its mean and variance are given. Allowing the dose interval to approach zero, the estimator is shown to be asymptotically normal and asymptotically…
