%description
Performs Wasserstein projections from the predictive distributions of any
model into the space of predictive distributions of linear models. We
utilize L1 penalties to also reduce the complexity of the model space.
This package employs the methods as described in Dunipace, Eric and
Lorenzo Trippa (2020) <doi:10.48550/arXiv.2012.09999>.
