On optimal schemes in progressive censoring

Abstract

Optimal censoring schemes in the model of progressive type II censoring are obtained for a location-scale family of distributions which includes exponential, uniform and Pareto distributions. In the one-parameter set-up the variance of the respective BLUE is used as an optimality criterion. In the two-parameter situation two criteria are applied which are based on the covariance matrix of the corresponding BLUEs, namely the trace and the determinant.Progressive type II censoring BLUE Censoring scheme
