What Are The Different Model Selection Methods? In this informative video, we will break down the various methods of model selection in regression analysis. Understanding how to choose the right model is essential for achieving accurate predictions and making sense of data. We will cover the Enter Method, which is straightforward and effective with a limited number of predictors. Additionally, we will discuss Stepwise Methods, including Forward Selection, Backward Elimination, and Stepwise Regression, each with its own unique approach to variable selection.

You will also learn about Best Subsets Regression, a technique that evaluates all combinations of variables to identify the optimal model based on specific criteria. We will highlight key statistics used to assess model quality, such as Adjusted R-squared and Predicted R-squared, along with the Akaike Information Criterion and Bayesian Information Criterion for model comparison.

Moreover, we will emphasize the importance of considering both statistical significance and theoretical relevance when selecting a model. This ensures that the chosen model is not only robust but also meaningful in the context of your research.
