Robust M Kibria Lukman estimator for linear regression model with outliers in the x-direction: simulations and applications

Science World Journal
The Ordinary Least Square (OLS) estimator remains Best Linear Unbiased Estimator (BLUE) when all the assumptions surrounding it stay intact, but at an iota of violation of the assumptions, it becomes inefficient and unstable. Some causes of the violation are the multicollinearity and the presence of extreme values (outliers).

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.

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 ...
