Features in the data

Open qucqu opened this issue 3 years ago • 2 comments

In 5.1.3 Illustration, I try to use your code and data to compute Lasso as you did in your book:

library(glmnet) y_penalized <- data_ml$R1M_Usd # Dependent variable x_penalized <- data_ml %>% # Predictors dplyr::select(all_of(features)) %>% as.matrix() fit_lasso <- glmnet(x_penalized, y_penalized, alpha = 1) # Model alpha = 1: LASSO

in dplyr::select(all_of(features)) %>% as.matrix(), since there is no "features" in your data, I cannot repeate your compution. Is the data in github is not the one you used in your book?

Thanks and regards, Mike

Dear Mike,

sorry for the inconvenience. The set of features is defined in Chapter 2 as: features <- colnames(data_ml[3:95])

With this it should work. Best,

Guillaule
