L‐Relationship between uncertainty and average seizure frequency in clinical trials of antiseizure medications

open access: yesEpilepsia, EarlyView.
Abstract Objective Antiseizure medications are approved based on clinical trials that demonstrate their efficacy as measured by reductions in seizure frequency (SF). When designing these trials, trialists must select inclusion criteria where SF can be reliably measured to maintain statistical power.

What happened after the epidemic? Equine influenza surveillance sheds light on sources and seasonal risk in the United Kingdom

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background The epidemiology of equine influenza (EI) in the United Kingdom has not been systematically described since the 2019 epidemic. Objectives To summarise UK EI surveillance (2020–2024), quantify outbreak seasonality and assess movement‐related sources. Study Design Retrospective observational analysis of national surveillance and horse

Differentially expressed heterogeneous overdispersion genes testing for count data.

open access: yesPLoS ONE
The mRNA-seq data analysis is a powerful technology for inferring information from biological systems of interest. Specifically, the sequenced RNA fragments are aligned with genomic reference sequences, and we count the number of sequence fragments ...

Double Generalized Beta-Binomial and Negative Binomial Regression Models

open access: yesRevista Colombiana de Estadística, 2017
Overdispersion is a common phenomenon in count datasets, that can greatly affect inferences about the model. In this paper develop three joint mean and dispersion regression models in order to fit overdispersed data.

An empirical method to estimate the effect of soil on the rate for transmission of damping‐off disease

open access: yes, 2004
The ability of some soils to suppress soil-borne diseases has been long recognised, but the underlying epidemiological mechanisms by which this occurs are largely unknown.• Using damping-off disease caused by Rhizoctonia solani, spreading through ...

A Comparison of Realized Measures of Integrated Volatility: Price Duration‐ vs. Return‐Based Approaches

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT We study the accuracy of a variety of parametric price duration‐based realized variance estimators constructed via various financial duration models and compare their forecasting performance with the performance of various nonparametric return‐based realized variance estimators.

Density dependence and the control of helminth parasites.

open access: yes, 2006
1. The transient dynamics and stability of a population are determined by the interplay between species density, its spatial distribution and the positive and negative density-dependent processes regulating population growth. 2.

Forecasting Count Data With Varying Dispersion: A Latent‐Variable Approach

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Count data, such as product sales and disease case counts, are common in business forecasting and many areas of science. Although the Poisson distribution is the best known model for such data, its use is severely limited by its assumption that the dispersion is a fixed function of the mean, which rarely holds in real‐world scenarios.

Lymphoma, multiple myeloma and leukaemia incidence in regions of Belarus most heavily contaminated by the Chernobyl accident

open access: yesInternational Journal of Cancer, EarlyView.
What's New? The 1986 Chernobyl accident led to widespread radioactive contamination across parts of Europe, with elevated childhood leukaemia rates observed in heavily affected areas of Ukraine. Data on long‐term haematological and other non‐thyroid cancer risk in the general population in heavily contaminated regions, however, remain limited.
