Summary
The most powerful test of the null hypothesisH 0:σ=σ 0 versus the alternative hypothesisH 1:σ=σ 1 based on a few selected sample quantiles is proposed here where σ is the scale parameter of the distribution and the location parameter μ is known. The quantiles are chosen from a large sample that is either complete or censored (singly-censored or doubly-censored). The relationship between the proposed test and the asymptotically best linear unbiased estimate (ABLUE) of the scale parameter is discussed.
