WebApr 11, 2024 · Mallows's Cp and Akaike information criterion (AIC) are common criteria for selecting the dimensionality of regression models, as an alternative to cross‐validation (CV) and nonparametric bootstrap. A key parameter in the calculation of Cp and AIC is the effective number of degrees of freedom of the model, or model complexity (d). WebSo CP if you click, there you go.

WebOct 15, 2005 · Mallows Cp statistic is used in multiple regression analysis to select models that contain smaller numbers of predictors from a larger number that is available for inclusion. Low values of Cp indicate regression models that are parsimonious yet still have good predictive ability.

Most of the previous Mallows-type averaging literature rely on linear regression models. In this paper, we extend this literature to adopt machine learning methods. We prove that the averaged estimator is asymptotically optimal in the sense of achieving

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.
