摘要
A robust LASSO-type penalized logistic regression based on maximum trimmed likelihood is proposed. The robustness property of the proposed method is stated and proved. A comparison of the performances of the proposed method with regular LASSO was conducted via simulations. (C) 2019 Elsevier B.V. All rights reserved.
