Feasible robust Liu estimator to combat outliers and multicollinearity effects in restricted semiparametric regression mode
Regression analysis frequently encounters two issues: multicollinearity among the explanatory variables, and the existence of outliers in the data set. Multicollinearity in the semiparametric regression model causes the variance of the ordinary least-squares estimator to become inflated. Furthermore...
