Model selection: Cp, AIC, BIC and adjusted R² - Medium

Webmination (R2) of the linear regression model.[9] developed an outlier detection and robust selection method that combined robust least angle regression with least trimmed squares regression on jack-knife subset.

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.
