LASSO回归求助
各位老师,求助~
最近有篇预测模型在修回,使用的是LASSO回归,以下是我的图和图释。
审稿人提出审稿意见:In the model evaluation index of lasso regression technology, the larger the c-index value, the better, and the smaller the deviance value, the better. The six features model chosen by the authors is not the optimal lambda value. There are two Vertical lines in Figure 2(A); please refine the C-index assessment (> cvfit <-cv.glmnet(x,y,family="cox",type.measure = "C",nfolds=10; > plot(cvfit)) and explain why the λ value with right dashed was chosen. 请问这个问题该怎么怎么回答,审稿人的代码是让我重新作图的意思吗?
