  • New Code for our HurdleDMR package for Julia is on github. It can be called from many other programming languages like Python and R. The package allows for computationally efficient distributed estimation of the multiple hurdles over parallel processes, generating sufficient reduction projections, and inverse regressions with selected text. It allows for elastic net type convex combinations of L1 (Lasso) and L2 (Ridge) regularization as in glmnet (Friedman et al., 2010), and for concave regularization paths as in gamlr (Taddy, 2017).
