Estimation of genetic parameters and trends for production traits of dairy cattle in Thailand using a multiple-trait multiple-lactation test day model [PDF]
Asian-Australasian Journal of Animal Sciences, 2020 Objective The objective of this study was to estimate the genetic parameters and trends for milk, fat, and protein yields in the first three lactations of Thai dairy cattle using a 3-trait,-3-lactation random regression test-day model.

Group Testing Regression Models with Fixed and Random Effects [PDF]
Biometrics, 2009 SummaryGroup testing, where subjects are tested in pools rather than individually, has a long history of successful application in infectious disease screening. In this article, we develop group testing regression models to include covariate effects that are best regarded as random.

Downscaling of Regional Air Quality Model Using Gaussian Plume Model and Random Forest Regression
Atmosphere, 2023 High PM10 concentrations are still a significant problem in many parts of the world. In many countries, including Poland, 50 μg/m3 is the permissible threshold for a daily average PM10 concentration.

A Bayesian Genomic Regression Model with Skew Normal Random Errors
G3: Genes, Genomes, Genetics, 2018 Genomic selection (GS) has become a tool for selecting candidates in plant and animal breeding programs. In the case of quantitative traits, it is common to assume that the distribution of the response variable can be approximated by a normal ...

Goodness of Fit Tests in Random Coefficient Regression Models [PDF]
Annals of the Institute of Statistical Mathematics, 1999 Random coefficient regressions have been applied in a wide range of fields, from biology to economics, and constitute a common frame for several important statistical models. A nonparametric approach to inference in random coefficient models was initiated by Beran and Hall.
