A simulation is used to evaluate the relative efficiencies of the proposed estimator and other six well-known ridge estimators with respect to the maximum likelihood estimator. The simulation results confirm that the relative efficiency of the proposed estimator is highest among other well-known estimators. Finally, a real-life data set is used to repeat the evaluation and the conclusion is the same as in the simulation186 leavesapplication/pdfengLogistic regression analysisA penalty function in binary logistic regressiontext--thesis--doctoral thesis10.14457/NIDA.the.2018.126
