R mallow's cp
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. Keywords: Multiple regression; variable election; model selection; …
