Unclusterable, underdispersed arrangement of insect‐pollinated plants in pollinator niche space [PDF]
Ecology, 2020 Abstract Pollinators can mediate facilitative or competitive relationships between plant species, but the relative importance of these two conflicting phenomena in shaping community‐wide pollinator resource use remains unexplored.

Frontiers in Veterinary Science, 2017 Antimicrobial resistance in livestock is a matter of general concern. To develop hygiene measures and methods for resistance prevention and control, epidemiological studies on a population level are needed to detect factors associated with antimicrobial ...

A Flexible Mixed Model for Clustered Count Data
Stats, 2022 Clustered count data are commonly modeled using Poisson regression with random effects to account for the correlation induced by clustering. The Poisson mixed model allows for overdispersion via the nature of the within-cluster correlation, however ...

An INAR(1) process for modeling count time series with equidispersion, underdispersion and overdispersion [PDF]
, 2017 We present a novel first-order nonnegative integer-valued autoregressive model for stationary count data processes with Bernoulli-geometric marginals based on a new type of generalized thinning operator.

Poverty and malaria morbidity in the Jirapa District of Ghana: A count regression approach
Cogent Economics & Finance, 2017 Malaria potentially affects everyone in the tropics and sub-tropics, however, the poor and vulnerable are worse affected mainly due to the socio-economic constraints that confront them. In Ghana, the Upper West Region, which is the poorest, is one of the

A Conway–Maxwell–Poisson Type Generalization of Hypergeometric Distribution
Mathematics, 2023 The hypergeometric distribution has gained its importance in practice as it pertains to sampling without replacement from a finite population. It has been used to estimate the population size of rare species in ecology, discrete failure rate in ...

Tropical Cyclone Research and Review, 2014 : This study evaluates ensemble forecasts with a stochastic kinetic energy backscatter scheme (SKEBS) to predict tropical cyclone (TC) genesis and also to characterize the related ensemble underdispersion. Several sets of ensemble forecasts are generated

The Gamma-count distribution in the analysis of experimental underdispersed data [PDF]
Journal of Applied Statistics, 2014 Event counts are response variables with non-negative integer values representing the number of times that an event occurs within a fixed domain such as a time interval, a geographical area or a cell of a contingency table. Analysis of counts by Gaussian regression models ignores the discreteness, asymmetry and heterocedasticity and is inefficient ...

Rapid Establishment of a Regular Distribution of Adult Tropical Drosophila Parasitoids in a Multi-Patch Environment by Patch Defence Behaviour. [PDF]
, 2011 Females of the larval parasitoid of Drosophila, Asobara citri, from sub-Saharan Africa, defend patches with hosts by fighting and chasing conspecific females upon encounter.

Revstat Statistical Journal, 2020 In most of the longitudinal studies, involving count responses, excess zeros are common in practice. Usually, the current response measurement in a longitudinal sequence is a function of previous outcomes.
