Combining Lasso and Liu type estimator in the linear regression model

Kayanan, M.; Wijekoon, P. (International Statistical Institute, 21-08-19)

The Ordinary Least Square Estimator (OLSE) has been widely used to estimate unknown parameters in the linear regression model. Since OLSE produces high variance on the estimates when multicollinearity exists among the ...
Performance of LASSO and Elastic net estimators in Misspecified Linear Regression Model

Kayanan, M.; Wijekoon, P. (Faculty of Science, University of Peradeniya, Sri Lanka, 16-09-19)

Ridge Estimator (RE) has been used as an alternative estimator for Ordinary Least Squared Estimator (OLSE) to handle multicollinearity problem in the linear regression model. However, it introduces heavy bias when the ...
