A note on the best invariant estimation of continuous probability distributions under mean square loss

Abstract

We consider the nonparametric estimation problem of continuous probability distribution functions. For the integrated mean square error we provide the statistic corresponding to the best invariant estimator proposed by Aggarwal (1955) and Ferguson (1967). The table of critical values is computed and a numerical power comparison of the statistic with the traditional Cramér-von Mises statistic is done for several representative distributions.
