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.

Asymptotic normality of kernel estimates in a regression model for random fields [PDF]
, 2008 We establish the asymptotic normality of the regression estimator in a fixed-design setting when the errors are given by a field of dependent random variables. The result applies to martingale-difference or strongly mixing random fields. On this basis, a

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 ...

A geothermal heat flow model of Africa based on random forest regression
Frontiers in Earth Science, 2022 Geothermal heat flow (GHF) data measured directly from boreholes are sparse. Purely physics-based models for geothermal heat flow prediction require various simplifications and are feasible only for few geophysical observables.

Animal, 2020 In order to map quantitative trait loci (QTLs) for allometries of body compositions and metabolic traits in chicken, we phenotypically characterize the allometric growths of multiple body components and metabolic traits relative to BWs using joint ...

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.
