Enhancing accuracy in modelling highly multicollinear data using alternative shrinkage parameters for ridge regression methods by Nadeem Akhtar, Muteb Faraj Alharthi

“…Using these new parameters, we develop three ridge condition-adjusted estimators (CAREs), referred to as CARE1, CARE2, and CARE3, which specifically designed to enhance predictive accuracy in datasets with significant multicollinearity and high error variance. The performance of the developed shrinkage estimators is rigorously evaluated through extensive simulation studies, using the Mean Square Error (MSE) criterion for accuracy assessment. …”
