In this paper we generalize different approaches of estimating the ridge parameter k proposed by Muniz et al. (Comput Stat, <CitationRef CitationID="CR16">2011</CitationRef>) to be applicable for logistic ridge regression (LRR). These new methods of estimating the ridge parameter in LRR are evaluated by means of Monte Carlo simulations...</citationref>

This paper considers several estimators for estimating the biasing parameter in the study of partial linear models in the presence of multicollinearity. After exhibiting the MSE of ridge estimator based on eigenvalues of design matrix, a simulation study has been conducted to compare the...
