本次介绍弹性网络(Elastic Net):一种用于回归分析的统计方法,它是岭回归(Ridge Regression)和lasso回归(Lasso Regression)的结合,主要区别在于 (1)将 L2 正则化应用于线性回归的损失函数时,称为Ridge回归。 (2)将 L1 正则化应用于线性回归的损失函数时,称为Lasso 回归 (3)将 L1 和 L2 正则化同时应用于线性回...
Cox modelVARIABLE SELECTIONREGRESSIONThe lasso and elastic net are popular regularized regression models for supervised learning. Friedman, Hastie, and Tibshirani (2010) introduced a computationally efficient algorithm for computing the elastic net regularization path for ordinary least squares regression, ...

A procedure based on a cross-validated regularized Cox regression using the Elastic Net penalty was applied to objectively identify predictors of death-censored graft failure. Hazard ratios were estimated by adjusting a multivariate Cox regression with the selected predictors. Results:...
