%description
Functions for computing split regularized estimators defined in
Christidis, Lakshmanan, Smucler and Zamar (2019) <arXiv:1712.03561>. The
approach fits linear regression models that split the set of covariates
into groups. The optimal split of the variables into groups and the
regularized estimation of the regression coefficients are performed by
minimizing an objective function that encourages sparsity within each
group and diversity among them. The estimated coefficients are then pooled
together to form the final fit.
