Does anyone know of package that implements a tobit model with L1 and L2 (lasso and ridge) penalties aka elastic net.
I am interested in an elastic net implementation of tobit because my variables are SNPs genotypes/dosage in Linkage disequilibrium and elastic net type models to well for that. The closest I found was The R Brq package implement the Bayesian Tobit quantile regression model with adaptive lasso penalty and will limit itself to an L1 penalty. p.s. I cannot do this by combining the penalized package and survreg as the penalized package does not yet allow for survreg models (as per Terry Therneau).
