%description
A scalable implementation of the highly adaptive lasso algorithm,
including routines for constructing sparse matrices of basis functions of
the observed data, as well as a custom implementation of Lasso regression
tailored to enhance efficiency when the matrix of predictors is composed
exclusively of indicator functions. For ease of use and increased
flexibility, the Lasso fitting routines invoke code from the 'glmnet'
package by default. The highly adaptive lasso was first formulated and
described by MJ van der Laan (2017) <doi:10.1515/ijb-2015-0097>, with
practical demonstrations of its performance given by Benkeser and van der
Laan (2016) <doi:10.1109/DSAA.2016.93>. This implementation of the highly
adaptive lasso algorithm was described by Hejazi, Coyle, and van der Laan
(2020) <doi:10.21105/joss.02526>.
