Graphical Evaluation of the Ridge-Type Robust Regression Estimators in Mixture Experiments
In mixture experiments, estimation of the parameters is generally based on ordinary least squares (OLS). However, in the presence of multicollinearity and outliers, OLS can result in very poor estimates. In this case, effects due to the combined outlier-multicollinearity problem can be reduced to ce...
