Abstract: We study large deviations of a widely used class of scale-free statistics under gamma distribution. We show that the constraints on the functions defining these statistics can be relaxed with respect to the previously obtained…

Abstract: The purpose of this study was to assess the gamma distribution as a model of the distribution of ages of cited references in corpora of scientific literature, and to derive inferences from the parameters of…

DOI: 10.1016/j.heliyon.2020.e05523
Abstract: The use of quantile functions of probability distributions whose cumulative distribution is intractable is often limited in Monte Carlo simulation, modeling, and random number generation. Gamma distribution is one of such distributions, and that has…

DOI: 10.1016/j.jas.2018.08.015
Abstract: Abstract Age-at-death profiles constructed from archaeozoological data have been used for decades to infer the goals of prehistoric herd management strategies. Several ‘ideal’ profiles have been proposed as models for the optimal kill-off profiles that…

Abstract: ABSTRACT In this paper, we propose a bimodal gamma distribution using a quadratic transformation based on the alpha-skew-normal model. We discuss several properties of this distribution such as mean, variance, moments, hazard rate and entropy…

Abstract: Abstract In this article, we aim to establish some theoretical properties of Izawa’s bivariate gamma distribution having equal shape parameters. First, we propose a procedure to obtain the maximum likelihood estimates and derive an expression…

DOI: 10.1080/10618600.2018.1537929
Abstract: Abstract The gamma distribution arises frequently in Bayesian models, but there is not an easy-to-use conjugate prior for the shape parameter of a gamma. This inconvenience is usually dealt with by using either Metropolis–Hastings moves,…
