WebChapter 24. Regularization. Chapter Status: Currently this chapter is very sparse. It essentially only expands upon an example discussed in ISL, thus only illustrates usage of the methods. Mathematical and conceptual details of the methods will be added later. Also, more comments on using glmnet with caret will be discussed. WebUse `alpha=1` and use the `lambda` that provided the minimum misclassification. Make sure to set the family to `binomial`. Once the model is fit, extract the coefficients to view the best model coefficients. ```{r} fit.lasso.min = glmnet(x, y, alpha = 1, lambda = cv.lasso $ lambda.min, family = " binomial ") coef(fit.lasso.min) # Should include ... how to take out yahoo malware in opera gx
