WebThe maximum R 2 improvement technique does not settle on a single model. Instead, it tries to find the "best" one-variable model, the ~best~ two-variable model, and so forth, … WebBut, remember that the p-values are adjusted for the other terms in the model. So, picking out the subset of significant predictors can be somewhat challenging. This task of identifying the best subset of predictors to include in the model, among all possible subsets of predictors, is referred to as variable selection. green haired guy from demon slayer

"WebThe models which yield the best (lowest) values of Cp will tend to be similar to those that yield the best (highest) values of adjusted R-squared, but the exact ranking may be slightly different. Other things being equal, the Cp criterion tends to favor models with fewer parameters, so it is a bit less likely to overfit the data. " - R best subset cp bic adjusted r2
