A Two Sample CRAMÉR-VON MISES Test for Randomly Censored Data
Authors:J A Koziol
Abstract:A CRAMÉR-VON MISES type statistic is introduced for testing the equality of the underlying survival distributions of two populations when observations are subject to arbitrary right censorship. The statistic is appropriate in testing problems where a two-sided alternative is of interest. The asymptotic distribution of the statistic is found; under certain circumstances, the limiting distribution coincides with that of a one sample CRAMÉR-VON MISES type statistic for randomly censored data investigated previously. Approximations to the asymptotic distribution are discussed; an example is given.
Keywords:CRAMÉ  R-VON MISES statistic  randomly censored data  survival analysis
