When Is Poisson Enough? A Likelihood-Based Comparison of Poisson and Negative Binomial GLMMs for Owl Nestling Call Counts

Axioms
Modeling count data using generalized linear mixed models (GLMMs) is a common practice in ecological research. However, datasets such as bird vocalization counts often display overdispersion, where the variance exceeds the mean, violating Poisson ...

Estuarine benthic diversity declines with temperature across a tropical–temperate gradient

Ecography, EarlyView.
Estuarine benthic sediments are important habitats that support ecosystem health and productivity, but the drivers of large‐scale patterns in benthic diversity are not well documented. Using 18S amplicon sequencing of 425 sediment DNA samples from estuaries spanning 20° of latitude along Australia's east coast, we assessed tropical–temperate patterns ...

Ultrafast oscillations in the human brain and their functional significance

Epilepsia, EarlyView.
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

SUDEP and mortality in developmental and epileptic encephalopathies: A meta‐analysis of randomized clinical trials and extension studies

Epilepsia, EarlyView.
Abstract Objective Developmental and epileptic encephalopathies (DEEs) are associated with high premature mortality and increased risk of sudden unexpected death in epilepsy (SUDEP). However, epidemiological data remain limited, particularly for specific syndromes such as Dravet syndrome (DS), Lennox–Gastaut syndrome (LGS), and infantile epileptic ...

Examining differences in phylogenetic composition enhances understanding of the phylogenetic structure of the shrub community in the northeastern Qinghai‐Tibetan Plateau

Ecology and Evolution, 2020
Periodic climatic oscillations and species dispersal during the postglacial period are two important causes of plant assemblage and distribution on the Qinghai‐Tibet Plateau (QTP).

Forecasting Duration in High‐Frequency Financial Data Using a Self‐Exciting Flexible Residual Point Process

Journal of Forecasting, EarlyView.
ABSTRACT This paper presents a method for forecasting limit order book durations using a self‐exciting flexible residual point process. High‐frequency events in modern exchanges exhibit heavy‐tailed interarrival times, posing a significant challenge for accurate prediction.

Estimation Parameters And Modelling Zero Inflated Negative Binomial

Cauchy: Jurnal Matematika Murni dan Aplikasi, 2016
Regression analysis is used to determine relationship between one or several response variable (Y) with one or several predictor variables (X). Regression model between predictor variables and the Poisson distributed response variable is called Poisson ...

A note on wadleys problem with overdispersion

, 1992
Wadley's problem results from quantal dose-response experiments when the basic distribution is Poisson, rather than binomial. We review approaches to the problem, with particular reference to using GLIM and incorporating overdispersion.
