%description
Stepwise regression is a statistical technique used for model selection.
This package streamlines stepwise regression analysis by supporting
multiple regression types(linear, Cox, logistic, Poisson, Gamma, and
negative binomial), incorporating popular selection strategies(forward,
backward, bidirectional, and subset), and offering essential metrics. It
enables users to apply multiple selection strategies and metrics in a
single function call, visualize variable selection processes, and export
results in various formats. StepReg offers a data-splitting option to
address potential issues with invalid statistical inference and a
randomized forward selection option to avoid overfitting. We validated
StepReg's accuracy using public datasets within the SAS software
environment. For an interactive web interface, users can install the
companion 'StepRegShiny' package.
