摘要：We study with some details a lifetime model of the class of beta generalized models, called the b eta inverse Rayleigh distribution, which is a special case of the Beta Fr′echet distribution. We provide a better foundation for some properties including quantile function, moments, mean deviations, Bonferroni and Lorenz curves, R′ enyi and Shannon entropies and order statistics. We fit the proposed mo del using maximum likelihood estimation to a real data set to illustrate its .exibility and p otentiality.
