✦ Synopsis

We present the results of an empirical power study of three prominent goodness-of-fit tests for exponentiality due to SHAPIBO and WILX (1972), DUBBLN (1976), and TIKW (1980) by considering the mixture-and the outlier-exponential models as alternatives. This study is on similar lines as those of DYEB and HUBIN (1981) and BALAKBISHNAN (1983). We show that Tiku's test is on the whole considerably more powerful than the other two tests.
