Abstract

Nonparametric predictive inference (NPI) is a statistical approach based on few assumptions about probability distributions, with inferences based on data. NPI assumes exchangeability of random quantities, both related to observed data and future observations, and uncertainty is quantified using lower and upper probabilities. In this paper, units from several groups are placed simultaneously on a lifetime experiment and times-to-failure are observed. The experiment may be ended before all units have failed. Depending on the available data and few assumptions, we present lower and upper probabilities for selecting the best group, the subset of best groups and the subset including the best group. We also compare our approach of selecting the best group with some classical precedence selection methods. Throughout, examples are provided to demonstrate our method.
