Explanation:
Detailed explanation-1: -To conclude, it is generally not advisable to use stepwise regression, especially if your research questions are theoretical. However, if you have a very large number of potential variables to use in your model. We recommend revisiting the literature to narrow your options down.
Detailed explanation-2: -The principal drawbacks of stepwise multiple regression include bias in parameter estimation, inconsistencies among model selection algorithms, an inherent (but often overlooked) problem of multiple hypothesis testing, and an inappropriate focus or reliance on a single best model.
