A test of goodness-of-fit based on Gini's index of spacings

摘要: This paper introduces a new test for goodness-of- t based on the Gini index which is sum over all pairs, of absolute di6erences observed spacings. We derive its exact and asymptotic distributions under null hypothesis, after showing that it distributionally equivalent to uniform observations unit interval. After discussion local powers this related tests, we provide simulated power comparisons, demonstrate better than other competitors considered, against wide variety alternatives. c
