WebStatistical Learning with Sparsity: The Lasso and Generalizations During the past decade there has been an explosion in computation and information technology. With it has come vast amounts of data in a variety of fields such as medicine, biology, finance, and marketing. WebFirst, due to the nature of the L1-penalty, the lasso tends to produce sparse solutions and thus facilitates model interpretation. Secondly, similar to ridge regression, lasso can outperform least squares in terms of prediction due to lower variance. Another advantage is that the lasso is computationally attractive due to its convex form. c# time a function
