It supports forward, backward,\nbidirectional, and best-subset selection under a range of\ncriteria. The package also supports stepwise regression to\nmultivariate settings, allowing multiple dependent variables to\nbe modeled simultaneously. Users can explore and combine\nmultiple selection strategies and criteria to optimize model\nselection. For enhanced robustness, the package offers optional\nrandomized forward selection to reduce overfitting, and a\ndata-splitting workflow for more reliable post-selection\ninference. Additional features include logging and\nvisualization of the selection process, as well as the ability\nto export results in common formats.", "License": "MIT + file LICENSE", "BugReports":
