STATA Blog: An introduction to the lasso in Stata
Why is the lasso interesting? The least absolute shrinkage and selection operator (lasso) estimates model coefficients and these estimates can be used to select which covariates should be included in a model. The lasso is used for outcome prediction and for inference about causal parameters. In this post, we provide an introduction to the lasso Read more about STATA Blog: An introduction to the lasso in Stata[…]
STATA Blog: Using the lasso for inference in high-dimensional models
High-dimensional models, which have too many potential covariates for the sample size at hand, are increasingly common in applied research. The lasso, can be used to estimate the coefficients of interest in a high-dimensional model. This post discusses commands in Stata 16 that estimate the coefficients of interest in a high-dimensional model. Mai mult
