Circular Polya distributions of order k

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Two circular Polya distributions of order k are derived by means of generalized urn models and by compounding, respectively, the type I and type II circular binomial distributions of order k of Makri and Philippou (1994) with the beta distribution. It is

Modelagem da ocorrência e da quantidade de chuva em Piracicaba Modeling of occurrence and rain amount in Piracicaba

open access: yesScientia Agricola, 1995
É proposto um modelo para descrever chuva diária de Piracicaba-SP em termos da sua ocorrência e da quantidade. Ambos, a ocorrência de dias com e sem chuva, quando considerados como seqüências de 31 dias a partir de determinada data, puderam ser bem ...

The Overlooked Potential of Generalized Linear Models in Astronomy-III: Bayesian Negative Binomial Regression and Globular Cluster Populations [PDF]

open access: yes, 2015
In this paper, the third in a series illustrating the power of generalized linear models (GLMs) for the astronomical community, we elucidate the potential of the class of GLMs which handles count data.

A beta-Poisson model for infectious disease transmission.

open access: yesPLoS Computational Biology
Outbreaks of emerging and zoonotic infections represent a substantial threat to human health and well-being. These outbreaks tend to be characterised by highly stochastic transmission dynamics with intense variation in transmission potential between ...

Statistical Tests for Extreme Precipitation Volumes

open access: yesMathematics, 2019
The analysis of the real observations of precipitation based on the novel statistical approach using the negative binomial distribution as a model for describing the random duration of a wet period is considered and discussed.

A vine copula mixed effect model for trivariate meta-analysis of diagnostic test accuracy studies accounting for disease prevalence [PDF]

open access: yes, 2015
A bivariate copula mixed model has been recently proposed to synthesize diagnostic test accuracy studies and it has been shown that it is superior to the standard generalized linear mixed model in this context.

Priors for Random Count Matrices Derived from a Family of Negative Binomial Processes

open access: yes, 2015
We define a family of probability distributions for random count matrices with a potentially unbounded number of rows and columns. The three distributions we consider are derived from the gamma-Poisson, gamma-negative binomial, and beta-negative binomial

Multivariate Jacobi and Laguerre polynomials, infinite-dimensional extensions, and their probabilistic connections with multivariate Hahn and Meixner polynomials [PDF]

open access: yes, 2011
Multivariate versions of classical orthogonal polynomials such as Jacobi, Hahn, Laguerre, Meixner are reviewed and their connection explored by adopting a probabilistic approach.

Assessing the adequacy of lymph node yield for different tumor stages of colon cancer by nodal staging scores

open access: yesBMC Cancer, 2017
Background According to the current official guidelines, at least 12 lymph nodes (LNs) are qualified as an adequate sampling for colon cancer patients. However, patients evaluated with less nodes were still common in the United States, and the prevalence

A Bayesian adaptive marker‐stratified design for molecularly targeted agents with customized hierarchical modeling [PDF]

open access: yes, 2019
It is well known that the treatment effect of a molecularly targeted agent (MTA) may vary dramatically, depending on each patient's biomarker profile. Therefore, for a clinical trial evaluating MTA, it is more reasonable to evaluate its treatment effect ...
