WitrynaThis is very appealing for big data analysis in that we don’t need to “read” the raw data again in a R session, which would be very time-consuming. The code below again fits a lasso-penalized linear model, and runs 10-fold cross-validation: system.time( {fit <- biglasso(X.bm, y)}) #> user system elapsed #> 0.128 0.004 0.132.
