Elastic Net Regression Explained, Step by Step
26. jun. 2021 — Elastic net is a combination of the two most popular regularized variants of linear regression: ridge and lasso.
Elastic net is a combination of the two most popular regularized variants of linear regression: ridge and lasso. Ridge utilizes an L2 penalty and lasso uses an L1 penalty. With elastic net, you don’t have to choose between these two models, because elastic net uses both the L2 and the L1 penalty! In practice, you will almost always want to use elastic net over ridge or lasso, and in this article you will learn everything you need to know to do so, successfully!

Frontiers | Evaluation of the lasso and the elastic net in genome-wide association studies
efter P Waldmann · 2013 · Citeret af 218 — The penalty parameter α determines how much weight should be given to either the lasso or ridge regression. The elastic net with α set to 0 is …
The number of publications performing genome-wide association studies (GWAS) has increased dramatically. Penalized regression approaches have been developed to overcome the challenges caused by the high dimensional data, but these methods are relatively new in the GWAS field. In this study we have compared the statistical performance of two methods (the least absolute shrinkage and selection operator—lasso and the elastic net) on two simulated data sets and one real data set from a 50 K genome-wide single nucleotide polymorphism (SNP) panel of 5570 Fleckvieh bulls. The first simulated data set displays moderate to high linkage disequilibrium between SNPs, whereas the second simulated data set from the QTLMAS 2010 workshop is biologically more complex. We used cross-validation to find the optimal value of regularization parameter λ with both minimum MSE and minimum MSE + 1SE of minimum MSE. The optimal λ values were used for variable selection. Based on the first simulated data, we found that the minMSE in general picked up too many SNPs. At minMSE + 1SE, the lasso didn’t acquire any false positives, but selected too few correct SNPs. The elastic net provided the best compromise between few false positives and many correct selections when the penalty weight α was around 0.1. However, in our simulation setting, this α value didn’t result in the lowest minMSE + 1SE. The number of selected SNPs from the QTLMAS 2010 data was after correction for population structure 82 and 161 …
