An Extended Laha-Lukacs Characterization Result Revisited.
Abstract
Recently Fosam and Shanbhag (1997) gave an extended version of the Laha-Lukacs characterization result based on a regression property, subsuming the Letac-Mora characterizations of the natural exponential families of distributions with variances as cubic functions of means. In the present note, we provide a new approach based on functional equations to arrive at the Fosam-Shanbhag result.
