Feasible robust Liu estimator to combat outliers and multicollinearity effects in restricted semiparametric regression mode [PDF]

Regression analysis frequently encounters two issues: multicollinearity among the explanatory variables, and the existence of outliers in the data set.

Quantile-based robust Kibria–Lukman estimator for linear regression model to combat multicollinearity and outliers: Real life applications using T20 cricket sports and anthropometric data

Kuwait Journal of Science
The performance of ordinary least squares (OLS) and ridge regression (RR) are influenced when outliers are present in y-direction with multicollinearity among independent variables. The robust RR with ridge parameters provides a biased estimator that has

Hybrid principal component regression estimation in linear regression [PDF]

In this paper, the principal component regression (PCR) estimators for regression parameters were studied in a linear regression model. After discussing the advantages and disadvantages of the classical PCR, we put forward three versions of hybrid PCR ...

Modeling and robust prediction of high heating values of municipal solid waste based on ultimate analysis [PDF]

The heating/calorific value of municipal solid waste (MSW) is essential in selecting or designing the appropriate waste to energy (WTE) systems. Experimental evaluation of the heating value of solid fuels is labor intensive, costly, and subject to ...
