%description
Provides very fast logistic regression with coefficient inferences plus
other useful methods such as a forward stepwise model generator (see the
benchmarks by visiting the github page at the URL below). The inputs are
flexible enough to accomodate GPU computations. The coefficient estimation
employs the fastLR() method in the 'RcppNumerical' package by Yixuan Qiu
et al. This package allows their work to be more useful to a wider
community that consumes inference.
