Statistical inference for lifetime data often involves right-censoring, with a variety of possible causes. This paper provides an overview of nonparametric predictive inference for comparison of multiple groups of data including right-censored observations. Different right-censoring schemes discussed are early termination of a lifetime experiment, progressive censoring and competing risks. Theoretical results are briefly stated, detailed justifications are presented elsewhere. The methods are illustrated and discussed via examples with data from the literature.
Keywords. Competing risks, early termination of experiment, nonparametric predictive inference, precedence testing, progressive censoring, right-censored data.
