%description
This system allows one to model a multi-variate, multi-response problem
with interaction effects. It combines the usual squared error loss for the
multi-response problem with some penalty terms to encourage responses that
correlate to form groups and also allow for modeling main and interaction
effects that exit within the covariates. The optimization method employed
is the Alternating Direction Method of Multipliers (ADMM). The
implementation is based on the methodology presented on Quachie Asenso,
T., & Zucknick, M. (2023) <doi:10.48550/arXiv.2303.11155>.
