ABSTRACT

This chapter is concerned with estimation of population parameters from censored samples, whereas the preceding chapters were concerned with complete samples. In life-span and reaction-time studies, it is common practice to cease observation before all specimens have failed. The resulting samples are accordingly said to be censored on the right. In a typical test, observation of survivors ceases with a single stage of censoring. Single-stage censoring has been fully considered by numerous writers, including Epstein and Sobel (1953), Epstein (1960), Gupta (1952), Hald (1949), Sarhan and Greenberg (1956, 1957, 1958), Cohen (1950, 1957, 1959, 1961), and Schneider (1986). Additional references to this and to related topics are listed in a bibliography compiled by Mendenhall (1958).
