A model of selective migration [PDF]

open access: yesHeredity, 1974
Individuals migrating between populations are normally assumed to be drawn at random from their base populations; migration is then a strong unifying force between the populations. Phenotypic assortment of migrants could however cause populations to diverge. A model is formulated to describe the effects of such selective migration on a metric character,

Antibiotic Resistances in Livestock: A Comparative Approach to Identify an Appropriate Regression Model for Count Data

open access: yesFrontiers in Veterinary Science, 2017
Antimicrobial resistance in livestock is a matter of general concern. To develop hygiene measures and methods for resistance prevention and control, epidemiological studies on a population level are needed to detect factors associated with antimicrobial ...

Source Model Selection for Deep Learning in the Time Series Domain

open access: yesIEEE Access, 2020
Transfer Learning aims to transfer knowledge from a source task to a target task. We focus on a situation when there is a large number of available source models, and we are interested in choosing a single source model that can maximize the predictive ...

Variable selection for the single index model [PDF]

open access: yes, 2007
We consider variable selection in the single-index model. We prove that the popular leave-m-out crossvalidation method has different behaviour in the single-index model from that in linear regression models or nonparametric regression models.

Developing an Optimal Spatial Predictive Model for Seabed Sand Content Using Machine Learning, Geostatistics, and Their Hybrid Methods

open access: yesGeosciences, 2019
Seabed sediment predictions at regional and national scales in Australia are mainly based on bathymetry-related variables due to the lack of backscatter-derived data. In this study, we applied random forests (RFs), hybrid methods of RF and geostatistics,

An Introduction to Model Selection

open access: yesJournal of Mathematical Psychology, 2000
This paper is an introduction to model selection intended for nonspecialists who have knowledge of the statistical concepts covered in a typical first (occasionally second) statistics course. The intention is to explain the ideas that generate frequentist methodology for model selection, for example the Akaike information criterion, bootstrap criteria,
