Any package which takes the likelihood function and do Lasso fitting?
I am looking for a package that takes the likelihood function and use the L1 penalty for MLE. More specifically I would like to fit the Hawke process model using the function likelihoodHawkes() in package "hawkes" https://cran.r-project.org/web/packages/hawkes/hawkes.pdf. Had a look at lasso packages at CRAN and couldn't find a general purpose one. Although I can use an optimizer, I guess it may be less efficient than specific ones for Lasso. I would be grateful for suggestions on packages or on how to efficiently use a general optimizer.
