Adjusted R-Square and Mallows

In statistics, Mallows's Cp, named for Colin Lingwood Mallows, is used to assess the fit of a regression model that has been estimated using ordinary least squares. It is applied in the context of model selection, where a number of predictor variables are available for predicting some outcome, and the goal is to find the best model involving a subset of these predictors. A small value of Cp means that the model is relatively precise. WebIt can be shown that when there are four candidate predictors — x 1, x 2, x 3 and x 4 — there are 16 possible regression models to consider.
