Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

The Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

A simple bivariate count data regression model [PDF]

This paper develops a simple bivariate count data regression model in which dependence between count variables is introduced by means of stochastically related unobserved heterogeneity components. Unlike existing commonly used bivariate models, we obtain

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

Archaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.

A priori ratemaking using bivariate poisson regression models [PDF]

In automobile insurance, it is useful to achieve a priori ratemaking by resorting to generalized linear models, and here the Poisson regression model constitutes the most widely accepted basis. However, insurance companies distinguish between claims with

Exploring the potential of cluster analysis in identifying disease phenotypes in CPPD: Moving from intuition to insight

Arthritis &Rheumatology, Accepted Article.
Background Calcium pyrophosphate deposition (CPPD) disease is a heterogeneous condition and is frequently misdiagnosed due to the different clinical presentations and variable disease progression. Aim of this study is to identify clinical phenotypes of CPPD disease by integrating real‐world data from two datasets. Methods Data from the COLCHICORT trial

Mixture of bivariate Poisson regression models with an application to insurance [PDF]

In a recent paper Bermúdez [2009] used bivariate Poisson regression models for ratemaking in car insurance, and included zero-inflated models to account for the excess of zeros and the overdispersion in the data set. In the present paper, we revisit this

Grandparent Prenatal Tobacco, Alcohol, Coffee, and Tea Consumption and Autism in the Third Generation

Autism Research, EarlyView.
ABSTRACT Exogenous prenatal exposures may affect neurodevelopment across multiple generations. We investigated grandmother and grandfather smoking, alcohol, coffee, and tea consumption during pregnancy in relation to their grandchildren's risk of autism spectrum disorder (ASD).

Bivariate Poisson and Diagonal Inflated Bivariate Poisson Regression Models in R [PDF]

In this paper we present an R package called bivpois for maximum likelihood estimation of the parameters of bivariate and diagonal inflated bivariate Poisson regression models. An Expectation-Maximization (EM) algorithm is implemented.
