Two properties of mixtures of exponential distributions

Abstract

Two properties characterizing mixtures of exponential distributions are obtained. The first result, suggested by Puri (1973), is improving in the case of a mixture of two exponentials. A result generalizing that of Nassar & Mahmoud (1985) is considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
