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 powerful than its competitors in cases where both apply, it may be used on types of data not previously discussed.

A test ia developed to determine whether the mean survival times are equal when dealing with paired survival dafe. We meume the data follow a bivariata exponential distribution for which the variables are conditionally independent. The unconditional distribution is derived in which the distribution
Flexible modelling in survival analysis can be useful both for exploratory and predictive purposes. Feed forward neural networks were recently considered for flexible non-linear modelling of censored survival data through the generalization of both discrete and continuous time models. We show that b
## Abstract The pairedβ__t__, sign, and signed rank tests were compared for samples from a bivariate exponential distribution. Each is a valid Ξ±βlevel test. One test was not uniformly more powerful than the others for all sample sizes, Ξ± levels, correlations, and alternative hypotheses considered,
