We previously proposed a class of ordered weighted logrank tests for analyzing censored survival data under order restrictions. However the power of these tests is asymmetrical with respect to possible alternative configurations and could be inferior to the non-ordered logrank test in extreme cases.
A coninion testing problem for a life table or survival date is to test the equality of two survival distributions when the data is both grouped end censored. Several tests have been proposed in the literature which require various assumptions about the censoring distributions. It is shown that if t
## Abstract The exact generalization of GEHAN's (1965) twoβsample test for arbitrarily censored survival data has been overlooked by subsequent work on the multisample problem. We give this general covariance matrix and show how it may be used in test procedures. While this permutation test is less
