Performance of variable selection methods using stability-based selection

open access: yesBMC Research Notes, 2017
Background Variable selection is frequently carried out during the analysis of many types of high-dimensional data, including those in metabolomics. This study compared the predictive performance of four variable selection methods using stability-based ...

Variable Selection for Spatial Logistic Autoregressive Models

open access: yesMathematics, 2022
When the spatial response variables are discrete, the spatial logistic autoregressive model adds an additional network structure to the ordinary logistic regression model to improve the classification accuracy. With the emergence of high-dimensional data

Variable Selection in ROC Regression [PDF]

open access: yesComputational and Mathematical Methods in Medicine, 2013
Regression models are introduced into thereceiver operating characteristic(ROC) analysis to accommodate effects of covariates, such as genes. If many covariates are available, the variable selection issue arises. The traditional induced methodology separately models outcomes of diseased and nondiseased groups; thus, separate application of variable ...

Study of Salary Differentials by Gender and Discipline

open access: yesStatistics and Public Policy, 2017
Although it is 45 years since legislation made gender discrimination on university campuses illegal, salary inequities continue to exist today. The seminal work in studying the existence of salary inequities is that of the American Association of ...

Stability Selection for Structured Variable Selection

open access: yesCoRR, 2017
In variable or graph selection problems, finding a right-sized model or controlling the number of false positives is notoriously difficult. Recently, a meta-algorithm called Stability Selection was proposed that can provide reliable finite-sample control of the number of false positives.

A-DVM: A Self-Adaptive Variable Matrix Decision Variable Selection Scheme for Multimodal Problems

open access: yesEntropy, 2020
Artificial Bee Colony (ABC) is a Swarm Intelligence optimization algorithm well known for its versatility. The selection of decision variables to update is purely stochastic, incurring several issues to the local search capability of the ABC.

Application of variable selection and dimension reduction on predictors of MSE’s development

open access: yesJournal of Big Data, 2019
Nature create variables using its character component, and variables are sharing characters from a vary small to relatively large scale. This results, variables to have from a vary different to a more similar character, and leads to have a relation ship.

Variable selection in multivariate multiple regression.

open access: yesPLoS ONE, 2020
IntroductionIn many practical situations, we are interested in the effect of covariates on correlated multiple responses. In this paper, we focus on estimation and variable selection in multi-response multiple regression models.

Group Variable Selection Methods with Quantile Regression: A Simulation Study. [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية
In many cases, covariates have a grouping structure that can be used in the analysis to identify important groups and the significant members of those groups. This paper reviews some group variable selection methods that utilize quantile regression.
