Beta-binomial/gamma-poisson regression models for repeated counts with random parameters
(Brazilian Statistical Association, 2011-07)
Beta-binomial/Poisson models have been used by many authors to model multivariate count data. Lora and Singer [Stat. Med. 27 (2008) 3366-3381] extended such models to accommodate repeated multivariate count data with ...
Multivariate models for correlated count data
(2013-04-18)
In this study, we deal with the problem of overdispersion beyond extra zeros for a collection of counts that can be correlated. Poisson, negative binomial, zero-inflated Poisson and zero-inflated negative binomial distributions ...

Beta-binomial/Poisson regression models for repeated bivariate counts
(JOHN WILEY & SONS LTD, 2008)
We analyze data obtained from a study designed to evaluate training effects on the performance of certain motor activities of Parkinson`s disease patients. Maximum likelihood methods were used to fit beta-binomial/Poisson ...
Spatiotemporal modeling of count data
(2021)
Modeling spatial and spatio-temporal data is a challenging task in statistics. In many applications, the observed data can be modeled using Gaussian, skew-Gaussian or even restricted random field models. However, in several ...
PeopleNet: A Novel People Counting Framework for Head-Mounted Moving Camera Videos
Traditional crowd counting (optical flow or feature matching) techniques have been upgraded to deep learning (DL) models due to their lack of automatic feature extraction and low-precision outcomes. Most of these models ...
A count model of financial inclusion in Ghana: evidence from living standards surveys
(Universidad ESAN. ESAN EdicionesPE, 2023-12-11)
Purpose: This paper aims to estimate the determinants of the intensity of use of financial inclusion by households in Ghana. Design/methodology/approach: Due to the reality of a household using one or more financial products ...
