Multivariate poisson-lognormal model for modeling related factors in crash frequency by severity
International Journal of Environmental Health Engineering, 2013 Aims: Traditionally, roadway safety analyses have used univariate distributions to model crash data for each level of severity separately. This paper uses the multivariate Poisson lognormal (MVPLN) models to estimate the expected crash frequency by two ...

Joint Modeling of Mixed Plasmodium Species Infections Using a Bivariate Poisson Lognormal Model [PDF]
The American Journal of Tropical Medicine and Hygiene, 2018 Infectious diseases often present as coinfections that may affect each other in positive or negative ways. Understanding the relationship between two coinfecting pathogens is thus important to understand the risk of infection and burden of disease caused by each pathogen.

The Poisson-Lognormal Model as a Versatile Framework for the Joint Analysis of Species Abundances [PDF]
Frontiers in Ecology and Evolution, 2021 Joint Species Distribution Models (JSDM) provide a general multivariate framework to study the joint abundances of all species from a community. JSDM account for both structuring factors (environmental characteristics or gradients, such as habitat type ...

A Bayesian Poisson-lognormal Model for Count Data for Multiple-Trait Multiple-Environment Genomic-Enabled Prediction [PDF]
G3: Genes, Genomes, Genetics, 2017 When a plant scientist wishes to make genomic-enabled predictions of multiple traits measured in multiple individuals in multiple environments, the most common strategy for performing the analysis is to use a single trait at a time taking into account ...

Late HIV diagnosis: An application of flexible Bayesian approaches to understand associated factors and time to diagnosis in Ireland, 2015–2024 [PDF]
HIV Medicine, Volume 27, Issue 11, Page 1881-1895, November 2026.Abstract Objectives Late HIV diagnosis is associated with increased morbidity, mortality and onward transmission. The proportion diagnosed late reflects the combined effects of testing delays, incidence and migration, complicating its interpretation. We analysed national HIV surveillance data for Ireland (2015–2024) to understand the factors associated

Multivariate Poisson Lognormal Modeling of Weather-Related Crashes on Freeways
Transportation Research Record: Journal of the Transportation Research Board, 2018 Adverse weather conditions are one of the primary causes of motor vehicle crashes. To identify the factors contributing to crashes during adverse weather conditions and recommend cost-effective countermeasures, it is necessary to develop reliable crash prediction models to estimate weather-related crash frequencies.
