Abstract
Modified sequential t tests based on M estimators are developed in this paper using the open, restricted and wedge schemes. Their performances are compared with those of the ordinary sequential t sequential trimmed t. and a nonparametric sequential sign rank test under normality and long-tailed distributions.
