Reproductive maturity and cone abundance vary with tree size and stand basal area for two widely distributed conifers

open access: yesEcosphere, 2020
Understanding potential limitations to tree regeneration is essential as rates of tree mortality increase in response to direct (extreme drought) and indirect (bark beetle outbreaks, wildfire) effects of a warming climate.

Multi-trait selection in multi-environments for performance and stability in cassava genotypes

open access: yesFrontiers in Plant Science, 2023
Genotype-environment interaction (GEI) presents challenges when aiming to select optimal cassava genotypes, often due to biased genetic estimates. Various strategies have been proposed to address the need for simultaneous improvements in multiple traits,

Bayes factor between Student t and Gaussian mixed models within an animal breeding context

open access: yesGenetics Selection Evolution, 2008
The implementation of Student t mixed models in animal breeding has been suggested as a useful statistical tool to effectively mute the impact of preferential treatment or other sources of outliers in field data. Nevertheless, these additional sources of

Posterior-based proposals for speeding up Markov chain Monte Carlo [PDF]

open access: yesRoyal Society Open Science, 2019
Markov chain Monte Carlo (MCMC) is widely used for Bayesian inference in models of complex systems. Performance, however, is often unsatisfactory in models with many latent variables due to so-called poor mixing, necessitating the development of ...

Mixed Shock Models

open access: yesBernoulli, 2001
The author studies system lifetimes that are associated with a cumulative shock model as follows: The system fails when the cumulative damage exceeds some threshold, or when a single large shock occurs. \textit{H. Li} and the reviewer [Stochastic Processes Appl. 58, No. 2, 205-216 (1995; Zbl 0833.60088); Appl. Probab. 34, No.

A Bayesian semiparametric latent variable model for mixed responses [PDF]

open access: yes, 2006
In this article we introduce a latent variable model (LVM) for mixed ordinal and continuous responses, where covariate effects on the continuous latent variables are modelled through a flexible semiparametric predictor. We extend existing LVM with simple

The analysis of longitudinal data using mixed model L-splines.

open access: yes, 2006
L-splines are a large family of smoothing splines defined in terms of a linear differential operator. This article develops L-splines within the context of linear mixed models and uses the resulting mixed model L-spline to analyze longitudinal data from ...
