The Gamma Generalized Normal Distribution: A Descriptor of SAR Imagery

Autor: Cordeiro, G. M., Cintra, R. J., Rêgo, L. C., Nascimento, A. D. C.

Publikováno v: Journal of Computational and Applied Mathematics, vol. 347, pages 257-272, February 2019

We propose a new four-parameter distribution for modeling synthetic aperture radar (SAR) imagery named the gamma generalized normal (GGN) by combining the gamma and generalized normal distributions. A mathematical characterization of the new distribu

Beta Generalized Normal Distribution with an Application for SAR Image Processing

Autor: Cintra, R. J., Rêgo, L. C., Cordeiro, G. M., Nascimento, A. D. C.

Publikováno v: A Journal of Theoretical and Applied Statistics, vol. 48, no. 2, 2014

We introduce the beta generalized normal distribution which is obtained by compounding the beta and generalized normal [Nadarajah, S., A generalized normal distribution, \emph{Journal of Applied Statistics}. 32, 685--694, 2005] distributions. The new

On Some Properties of the Beta Inverse Rayleigh Distribution

Autor: Leão, J., Saulo, H., Bourguignon, M., Cintra, R. J., Rêgo, L. C., Cordeiro, G. M.

Publikováno v: Chilean Journal of Statistics, vol. 4, no. 2, pages 111-131, September 2013

We study with some details a lifetime model of the class of beta generalized models, called the beta inverse Rayleigh distribution, which is a special case of the Beta Fr\'echet distribution. We provide a better foundation for some properties includi

The McDonald Normal Distribution

Autor: Cordeiro, G. M., Cintra, R. J., Rêgo, L. C.

A five-parameter distribution called the McDonald normal distribution is defined and studied. The new distribution contains, as special cases, several important distributions discussed in the literature, such as the normal, skew-normal, exponentiated

On Some Properties of the Beta Normal Distribution

Autor: Rêgo, L. C., Cintra, R. J., Cordeiro, G. M.

Publikováno v: Communications in Statistics - Theory and Methods, Volume 41, Issue 20, 2012

The beta normal distribution is a generalization of both the normal distribution and the normal order statistics. Some of its mathematical properties and a few applications have been studied in the literature. We provide a better foundation for some

On a Density for Sets of Integers

Autor: Cintra, R. J., Rêgo, L. C., de Oliveira, H. M., de Souza, R. M. Campello

A relationship between the Riemann zeta function and a density on integer sets is explored. Several properties of the examined density are derived.

Report

An Extension of the Dirichlet Density for Sets of Gaussian Integers

Autor: Rêgo, L. C., Cintra, R. J.

Publikováno v: Can. Math. Bull. 56 (2013) 161-172

Several measures for the density of sets of integers have been proposed, such as the asymptotic density, the Schnirelmann density, and the Dirichlet density. There has been some work in the literature on extending some of these concepts of density to
