Nonparametric maximum-likelihood estimation of within-set ranking errors in ranked set sampling. (English) Zbl 1203.62043

Summary: A distribution-free statistical inference for the quality of within-set judgement ranking information is developed for ranked set samples. The judgement ranking information is modelled through the L. L. Bohn and D. A. Wolfe (BW) model [J. Am. Stat. Assoc. 87, No. 418, 552–561 (1992; Zbl 0781.62051); ibid. 89, No. 425, 168–176 (1994; Zbl 0800.62251)]. The cumulative distribution function and the parameters of BW model are estimated by maximising nonparametric likelihood functions. A missing data model is introduced to construct an efficient computational algorithm. The advantages of the new estimators are that they require essentially no assumption on the underlying distribution function, which provides an estimate of the quality of within-set ranking information, and that they lead to a valid statistical inference even under imperfect ranking. The proposed estimators are applied to a water flow data set to estimate judgement ranking information and underlying distribution function.
