Tīmeklis2024. gada 15. nov. · Our lasso picked all 15 of the predictors we used to create our response variable – nice! It also picked 68 other predictors that weren’t in our model, but notice that the estimated coefficients for them (mean = 0) are much smaller than for the ‘true’ variables (mean = 0.89). This suggests that our lasso did a good job identifying … Tīmeklis2024. gada 26. aug. · lambda.1se 表示 误<=最小误+1se时最大lambda 正常lambda.min< lambda.1se 。 用lambda.1se 模型的一般误会更好些。。 用 …
