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. The methodology is described in Li et
        al. (2026) <doi:10.32614/RJ-2026-005>.
