Enhancing Predictive Performance of the Logistic Two-Parameter Estimator under Multicollinearity

Kayathiri, T.; Kayanan, M.; Wijekoon, P. (Institute of Applied Statistics, Sri Lanka, 2024)

"This study aimed to propose a new estimator named Modified Logistic Two-Parameter Estimator (MLTPE) with the best predictive performance in logistic regression when multicollinearity exists. The performance of the proposed ...
A new shrinkage-based estimator for logistic regression under multicollinearity: The James-Stein logistic Liu estimator (JSLLE)

Kayathiri, T.; Kayanan, M.; Wijekoon, P. (Young Scientists’ Association, National Institute of Fundamental Studies, Sri Lanka, 2025)

Logistic regression is a widely used method for analyzing binary outcomes in various fields, including healthcare and finance. The Maximum Likelihood Estimator (MLE) is the standard technique for estimating parameters in ...
