The behaviour of group sequential tests in the two-sample problem is investigated if one replaces the classical non-robust estimators in the t-test statistic by modern robust estimators of location and scale. Hampel's 3-part redescending M-estimator 25A used in the Princeton study and the robust...

Macro models generally assume away heterogeneous welfare in assessing policies. We investigate here within two aggregative models ó one with a representative agent, the other a long-used forecasting model of the UK ó whether allowing for di§erences in welfare functions (speciÖcally between...

In this paper, we develop a modified maximum likelihood (MML) estimator for the multiple linear regression model with underlying student t distribution. We obtain the closed form of the estimators, derive the asymptotic properties, and demonstrate that the MML estimator is more appropriate for...
