…, DP Green, AG Greenwald, JD Hadfield… - Nature human …, 2018 - nature.com
The lack of reproducibility of scientific studies has caused growing concern over the credibility
of claims of new discoveries based on ‘statistically significant’findings. There has been …

MCMC methods for multi-response generalized linear mixed models: the MCMCglmm R package

JD Hadfield - Journal of statistical software, 2010 - jstatsoft.org
Generalized linear mixed models provide a flexible framework for modeling a range of data,
although with non-Gaussian response variables the likelihood cannot be obtained in closed …

The misuse of BLUP in ecology and evolution

JD Hadfield, AJ Wilson, D Garant… - The American …, 2010 - journals.uchicago.edu
Best linear unbiased prediction (BLUP) is a method for obtaining point estimates of a
random effect in a mixed effect model. Over the past decade it has been used extensively in …

How to separate genetic and environmental causes of similarity between relatives

LEB Kruuk, JD Hadfield - Journal of evolutionary biology, 2007 - academic.oup.com
Related individuals often have similar phenotypes, but this similarity may be due to the
effects of shared environments as much as to the effects of shared genes. We consider here …

[PDF][PDF] Horizontally transmitted symbionts and host colonization of ecological niches

LM Henry, J Peccoud, JC Simon, JD Hadfield… - Current biology, 2013 - cell.com
Facultative or "secondary" symbionts are common in eukaryotes, particularly insects. While
not essential for host survival, they often provide significant fitness benefits [1–5]. It has been …
