Naderi M, Arabpour A, Jamalizadeh A. On the Finite Mixture Modelling via Normal Mean-variance Birnbaum-Saunders Distribution. JIRSS. 2017; 16 (1) :33-51

Abstract:   (647 Views)

‎This paper presents a new finite mixture model using the normal mean-variance‎ ‎mixture of Birnbaum-Saunders distribution‎. ‎The proposed model is multimodal with wider‎ ‎ranges of skewness and kurtosis‎. ‎Moreover‎, ‎it is useful for modeling highly asymmetric data in various theoretical and applied statistical problems‎. ‎The maximum likelihood‎ ‎estimates of the parameters of the model are computed iteratively by feasible‎ ‎EM algorithm‎. ‎To illustrate the finite sample properties and performance of the‎ ‎estimators‎, ‎we conduct a simulation study and illustrate the usefulness of the new model by analyzing a real dataset‎.
