Modeling Count Distributions via Skewness–Kurtosis Orthogonal Expansions

open access: yesMathematics
We develop a semi-parametric framework for representing discrete probability mass functions through orthogonal polynomial representations. Classical count models, such as the Poisson and negative binomial distributions, impose restrictive structural ...

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Can Knowledge of Taxi Drivers’ Intentions to Commit Traffic Violations Predict Crash Frequency?

open access: yesSafety
Taxi drivers are a group with high driving exposure and are involved in a significant number of urban traffic casualties. Using two modelling approaches, this study examines whether the intention to speed, as measured by the Theory of Planned Behaviour ...

Modeling effects of environmental conditions and hunter activity on Montezuma quail harvest in Arizona

open access: yesThe Journal of Wildlife Management, EarlyView.
Models of spatiotemporal variation in hunter harvest show that monsoon precipitation and changes in hunter behavior and composition are the primary drivers underlying variation in annual harvest of Montezuma quail. The demographic structure of the previous year's harvest was also strongly associated with the magnitude and rate of annual harvest ...

Control of glycaemia and its related factors in patients with type 2 diabetes, north of Iran: generalized linear mixed models and prevalence of overdispersion in patients [PDF]

open access: yesHealth Science Monitor
Background & Aims:  Glycemic control is very important to prevent or suspend complications in patients with type 2 diabetes (PT2D). The aim of this study was to investigate the status of glycemic control and its related factors in patients with type 2 ...

Quantifying harvest of barren‐ground caribou off a winter road in the Northwest Territories – An Indigenous Guardian‐led initiative

open access: yesThe Journal of Wildlife Management, EarlyView.
The North Slave Métis Alliance's Indigenous Guardianship Program conducted on‐the‐ground patrols monitoring caribou interactions with the Tibbitt to Contwoyto Winter road and quantify caribou harvest. Quantifying the impacts of winter roads on barren‐ground caribou herds supports community members’ commitment to safeguarding their traditional territory

Generalized Additive Models for Location Scale and Shape (GAMLSS) in R

open access: yesJournal of Statistical Software, 2007
GAMLSS is a general framework for fitting regression type models where the distribution of the response variable does not have to belong to the exponential family and includes highly skew and kurtotic continuous and discrete distribution.

Sensory difference testing: The problem of overdispersion and the use of beta binomial statistical analysis

open access: yes, 2019
An increase in variance (overdispersion) can occur when a binomial statistical analysis is applied to sensory difference test data in which replicate sensory evaluations (tastings) and multiple evaluators (judges) are combined to increase the sample size.
