Modelling and diagnostic tests for Poisson and negative-binomial count time series

Aleksandrov, Boris; Weiß, Christian H.; Nik, Simon; … - In: Metrika 87 (2023) 7, pp. 843-887

When modelling unbounded counts, their marginals are often assumed to follow either Poisson (Poi) or negative binomial (NB) distributions. To test such null hypotheses, we propose goodness-of-fit (GoF) tests based on statistics relying on certain moment properties. By contrast to most approaches...

Multi-Type Branching Processes Modeling of Nosocomial Epidemics

Mohamed, Zeinab; Oraby, Tamer - In: Stochastics and Quality Control 32 (2017) 2, pp. 63-75

Abstract Nosocomial epidemics are infectious diseases which spread among different types of susceptible individuals in a health-care facility. To model this type of epidemics, we use a multi-type branching process with a multivariate negative binomial offspring distribution. In particular, we...

Bivariate Negative Binomial Generalized Linear Models for Environmental Count Data

Iwasaki, Masakazu; Tsubaki, Hiroe - In: Journal of Applied Statistics 33 (2006) 9, pp. 909-923

We propose a new bivariate negative binomial model with constant correlation structure, which was derived from a … dependent structure with indices of dispersion. In this paper we first derive a new bivariate negative binomial distribution as … bivariate negative binomial models to two correlated environmental data sets. …

An alternative bivariate zero-inflated negative binomial regression model using a copula

So, Sunha; Lee, Dong-Hee; Jung, Byoung Cheol - In: Economics Letters 113 (2011) 2, pp. 183-185

We propose an alternative bivariate zero-inflated negative binomial (BZINB) regression model based on a copula. The empirical result shows that the proposed model performs better than the existing BZINB models in terms of the maximum log-likelihood and the AIC.

Composite Likelihood Modeling of Neighboring Site Correlations of DNA Sequence Substitution Rates

Deng, Ling; Moore, Dirk - In: Statistical Applications in Genetics and Molecular Biology 8 (2009) 1, pp. 6-6

Sequence data from a series of homologous DNA segments from related organisms are typically polymorphic at many sites, and these polymorphisms are the result of evolutionary processes. Such data may be used to estimate the substitution rates as well as the variability of these rates. Careful...

Gender effect on housework allocation: Evidence from Spanish two-earner couples

Álvarez, Begoña; Miles, Daniel - In: Journal of Population Economics 16 (2003) 2, pp. 227-242

In this paper we study the reasons behind the asymmetric distribution of housework within Spanish two-earner couples. Spouses' housework times are estimated jointly in a bivariate framework using data from the 1991 Work Situation and Time Use Survey. In order to understand the impact of...
