✦ Synopsis

This work discumes how two sample t-tests behave when applied to data that may violate the classical statistical assumptions of independence, heteroscedasticity and Gaussianity. The usual two sample t-statistic based on a pooled variance estimate and the Welch-Aspin stathtic me treated in detail. Practical "rules-of-thumb" are given along with their applications to various examples so that readers will easily be able to use such tests on their own data sets.

A robust two-sample Student t-type procedure baed on symmetrically censored samples propoeed by TIKIJ (1980, 19828, b) is studied from the Bayesian point of view. The effect of aaymmetric censoring on this procedure is investigated and a good approximation to its posterior distribution in this ease

If the sample size for a t-test is calculated on the basis of a prior estimate of the variance then the power of the test at the treatment di!erence of interest is not robust to misspeci"cation of the variance. We propose a t-test for a two-treatment comparison based on Stein's two-stage test which
