WebSep 23, 2024 · A variable selection method is a way of selecting a particular set of independent variables (IVs) for use in a regression model. This selection might be an attempt to find a ‘best’ model, or it might be an attempt to limit the number of IVs when there are too many potential IVs. There are a number of commonly used methods which I call ...

WebVariable Selection in Multiple Regression. When we fit a multiple regression model, we use the p -value in the ANOVA table to determine whether the model, as a whole, is significant. A natural next question to ask is which predictors, among a larger set of all potential predictors, are important. We could use the individual p -values and refit ...

WebWith any variable selection method, it is important to keep in mind that model selection cannot be divorced from the underlying purpose of the investigation. Variable selection tends to amplify the statistical signicance of the variables that stay in the model. Variables that are dropped can still be correlated with the response.
