ShadowVIMP: permutation-based multiple testing-controlled variable selection [PDF]

BMC Bioinformatics
Background Identifying relevant biomarkers is critical in clinical research and precision medicine, particularly when analysing high-dimensional data. Random forests (RFs) are promising for such settings due to their flexibility, ease of use, and their ...

Systematic Review of Variable Selection Bias in Species Distribution Models for Aedes vexans (Diptera: Culicidae) [PDF]

Insects
We conducted a systematic literature review, following PRISMA guidelines, to assess whether existing species distribution models for Aedes vexans reflect its known ecological requirements.

Variable selection for decentralized control [PDF]

Modeling, Identification and Control, 1992
Decentralized controllers (single-loop controllers applied to multivariable plants) are often preferred in practice because they are robust and relatively simple to understand and to change. The design of such a control system starts with pairing inputs (

Gibbs Variable Selection Using BUGS

Journal of Statistical Software, 2002
In this paper we discuss and present in detail the implementation of Gibbs variable selection as defined by Dellaportas et al. (2000, 2002) using the BUGS software (Spiegelhalter et al. , 1996a,b,c).

Variable Selection of Lasso and Large Model

IEEE Access, 2023
In order to clarify the variable selection of Lasso, Lasso is compared with two other variable selection methods AIC and forward stagewise. First, the variable selection of Lasso was compared with that of AIC, and it was discovered that Lasso has a wider

Performance of variable selection methods using stability-based selection

BMC 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

Mathematics, 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

Study of Salary Differentials by Gender and Discipline

Statistics 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 ...

Variable selection in social-environmental data: sparse regression and tree ensemble machine learning approaches

BMC Medical Research Methodology, 2020
Background Social-environmental data obtained from the US Census is an important resource for understanding health disparities, but rarely is the full dataset utilized for analysis.
