The confounding effects of distribution mixtures on some basic methods for handling stable-Paretian distributions

Article Abstract:

The performance of fundamental stable-Paretian (SP) parameter-estimation and SP hypothesis-testing methods for simple mixture-distributions were analyzed to determine the applicability of SP methods on SP distributions. Applications of basic SP methods to mixtures of SP distributions and testing methods for evaluating the performance of the SP hypothesis for various business/economic variables provided misleading or unreliable answers. Furthermore, new portfolio-selection models and statistical procedures should be developed to handle SP mixtures properly.
