Fixed-Width Estimation of the Mean of Logistic Response Function Using Spearman-Karber Estimator

In this paper we study the asymptotic properties of the sequential fixed-width rule developed for the estimation of the mean of the logistic response function based on the quantal responses observed at equally spaced dose levels. The Spearman-Karber (S-K) and Spearman-type variance (S-T-V) estimator are used for the mean and variance, respectively, in the sequential estimation. We compute the coverage probabilities and stop
