Regression Models for Count Data in R [PDF]
The classical Poisson, geometric and negative binomial regression models for count data belong to the family of generalized linear models and are available at the core of the statistics toolbox in the R system for statistical computing.

Hybrid Granular–Elastomer Jamming With Confinement‐Mediated Stiffening
Advanced Intelligent Systems, EarlyView.A granular–elastomer hybrid jamming medium enables isotropic, repeatable stiffness modulation by exploiting vacuum‐induced confinement of an elastomeric network rather than particle friction. The actuator supports large 3D deformations (bending, folding, and twisting), retains programmed shapes when unjammed, and achieves an ~8× stiffness increase and ...

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.

American Journal of Agricultural Economics, EarlyView.Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Floral traits and hermaphrodite abundance shape female advantage in a gynodioecious plant
American Journal of Botany, EarlyView.Abstract Premise Gynodioecy is maintained through female advantage in seed fitness that depends on the sex ratio of a population. We hypothesized that females of Silene acaulis would exhibit floral traits associated with elevated outcross pollination and that sex ratio would impact pollen limitation and inbreeding depression such that female advantage ...

Insurance: an R-Program to Model Insurance Data [PDF]
Data sets from car insurance companies often have a high-dimensional complex dependency structure. The use of classical statistical methods such as generalized linear models or Tweedie?s compound Poisson model can yield problems in this case. Christmann (

Australian Journal of Social Issues, EarlyView.ABSTRACT Most adults with neurological disability rely on general practitioners for managing and preventing health complications. This study analysed patterns of general practice service utilisation among National Disability Insurance Scheme (NDIS) participants with neurological disability and compared these with people who are not NDIS participants ...
