On characterization of distribution by conditional expectation
We show that, under mild conditions on h(1), E(h(X)∣X>y) charactarizes the distribution function of K, and exhibit a method of obtainig the distribution whenever E(h(X)∣X>y) is known, in the continuos and in the discrete case The results of Shenbhag (1970) aad Hamdan (1972) follow immediately.
