Share WebI want to fit a linear regression to the data: fit = lm (y ~ d$x1 + d$x2 + d$y2) Is there a way to write the formula, so that I don't have to write out each individual covariate? For example, something like fit = lm (y ~ d) (I want each variable in the data frame to be a covariate.) WebFirst, we demonstrate how we can use this new version of glmnet to fit ordinary least squares with the elastic net penalty. We set up some fake data: set.seed (1) x <- matrix ( rnorm (500), ncol = 5) y <- rowSums (x[, 1:2]) + rnorm (100) The function calls below demonstrate how we would fit the model with the old and new family parameter options. 額 シワ取りクリーム
