Description: This model fitting tool incorporates cyclic coordinate
        descent and majorization-minimization approaches to fit a
        variety of regression models found in large-scale observational
        healthcare data.  Implementations focus on computational
        optimization and fine-scale parallelization to yield efficient
        inference in massive datasets.  Please see: Suchard, Simpson,
        Zorych, Ryan and Madigan (2013) <doi:10.1145/2414416.2414791>.
