Interference of sample size on multicollinearity diagnosis in path analysis [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2018
: The objective of this work was to evaluate the interference of sample size on multicollinearity diagnosis in path analysis. From the analyses of productive traits of cherry tomato, two Pearson correlation matrices were obtained, one with severe ...

Decreasing Multicollinearity [PDF]

open access: yesSociological Methods & Research, 1979
When the multicollinearity among the independent variables in a regression model is due to the high correlations of a multiplicative function with its constituent variables, the multicollinearity can be greatly reduced by centering these variables around minimizing constants before forming the multiplicative function. The values of these constants that

Multicollinearity

open access: yes, 2023
In this paper, I explore the symptoms of multicollinearity, detection methods for multiple linear regression models, examples using simulated and real-world data, and possible remedies.

A Comparative Study of Multivariate Analysis Techniques for Highly Correlated Variable Identification and Management [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2020
In this work we attempt is to locate and analyze via multivariate analysis techniques, highly correlated covariates (factors) which are interrelated with the Gross Domestic Product and therefore are affecting either on short-term or on long-term its ...

On the Performance of Jackknife Based Estimators for Ridge Regression

open access: yesIEEE Access, 2021
Regression techniques are generally used to predict a response variable using one or more predictor variables. In many fields of study, the regressors can be highly intercorrelated, which leads to the problem of multicollinearity.

A Monte Carlo simulation framework on the relative performance of system estimators in the presence of multicollinearity

open access: yesCogent Social Sciences, 2021
The correctness and reliability of findings and\recommendations of empirical studies conducted by social and economic researchers depend largely on the efficiency of the econometrics methodologies employed in such studies. Of particular interest are such

Spatial Estimation of Regional PM2.5 Concentrations with GWR Models Using PCA and RBF Interpolation Optimization

open access: yesRemote Sensing, 2022
In recent years, geographically weighted regression (GWR) models have been widely used to address the spatial heterogeneity and spatial autocorrelation of PM2.5, but these studies have not fully considered the effects of all potential variables on PM2.5 ...

A New Quantile-Based Approach for LASSO Estimation

open access: yesMathematics, 2023
Regularization regression techniques are widely used to overcome a model’s parameter estimation problem in the presence of multicollinearity. Several biased techniques are available in the literature, including ridge, Least Angle Shrinkage Selection ...
