Mallow's cp in r

WebAIC [Akaike (1973)], Mallows' Cp [Mallows (1973)] and the Bayesian informa-tion criterion BIC [Schwarz (1978)], use a fixed penalty on the size of a model. Some new variable selection procedures suggest the use of a data adaptive penalty to replace fixed penalties [i.e., Bai, Rao and Wu (1999) and Shen and Ye (2002)]. WebMallows version for a sub-model of size p is C p=SSE [p]σˆ r (2)−n+2p. Note that σˆ r 2 comes from the full model. This is used to compare the suitability of various sub-models. One can use either an all subsets approach or a stepwise approach (just forward, or forward and backward, etc.). Mallows (1964, 1966, oral presentations; 1973 ...

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. WebMallows, C.L. (1973) Some Comments on CP.
