| Abstract | The problem of two-sample survival comparisons has been investigated by several authors. Pepe and Fleming (1989) introduced a test for right-censored survival data. Petroni and Wolfe (1994) considered a similar test where the survival times can only take on a finite number of values. We extend their tests to general types of interval-censored data and introduce a class of test statistics based on inte- grated weighted differences between the two estimated survival functions.We derive the asymptotic distributions of the generalized test statistics, present a bootstrap test procedure and apply the proposed method to a set of interval-censored data from a breast cancer study. |
