A-optimal and D-optimal censoring plans in progressively Type-II right censored order statistics

Abstract

We study how the marginal distribution and Fisher information matrix of progressively Type-II right censored order statistics change when the progressive censoring plan changes. We consider the missing information and its connection with Fisher information matrix to determine the A-optimal and D-optimal plans in multiparameter case. We provide a simple expression and a simple way of determining an optimal censoring plan among a class of one-step censoring plans. Finally we give examples to illustrate results.
