"Tīmeklis2024. gada 9. jūl. · The log lambda on the x-axis is from the same vector of lambda values that lambda.min came from. Just be aware that due to the nature of cross validation, you can get different values for lambda.min if you run cv.glmnet again. So, your mark on the x-axis would be the lambda.min from a particular call of cv.glmnet. " - Lambda.min and lambda.1se
