Hazard functions for the gamma-order generalized distributions
Research in StatisticsThe target of this article is to evaluate the hazard function for the γ-order distributions, already proposed. As the γ-order Normal distribution acts as a mother distribution for the γ-order: Lognormal, Chi-square, Rayleigh, and Maxwell-Boltzmann, we ...

Shape theory via polar decomposition [PDF]
, 2010 This work proposes a new model in the context of statistical theory of shape, based on the polar decomposition. The non isotropic noncentral elliptical shape distributions via polar decomposition is derived in the context of zonal polynomials, avoiding ...

Smoothing-inspired lack-of-fit tests based on ranks
, 2008 A rank-based test of the null hypothesis that a regressor has no effect on a response variable is proposed and analyzed. This test is identical in structure to the order selection test but with the raw data replaced by ranks. The test is nonparametric in

Algunas integrales indefinidas que contienen a la función hipergeométrica generalizada
Ingeniería y Ciencia, 2009 En 1999 Nina Virchenko consideró la generalización de la función hipergeométrica de Gauss 2R 1(a, b; c; τ ; z) con un conjunto de fórmulas de recurrenciay de diferenciación.

Shape Theory via QR decomposition [PDF]
, 2010 This work sets the non isotropic noncentral elliptical shape distributions via QR decomposition in the context of zonal polynomials, avoiding the invariant polynomials and the open problems for their computation.

Remarks on a Paper of Lee and Lim [PDF]
, 2014 Lee and Lim (2009) state three characterizations of Loamax, exponential and power function distributions, the proofs of which, are based on the solutions of certain second order non-linear differential equations.
