CV_REGRESS: Stata module to estimate the leave-one-out error for linear regression models

Statistical Software Components from Boston College Department of Economics

Abstract: cv_regress uses the shortcut that relies on the leverage statistics to estimate the leave-one-out error, which is typically used in the estimation of Cross-Validation Statistics. For the correct implementation, the OLS model needs to be estimated using -regress- before this program is executed. cv_regress reports three goodness-of-fit measures: the root mean squared error (RMSE), the mean absolute error (MAE), and the pseudo-R2 (the square of the correlation coefficient of the predicted and observed values of the dependent variable). It also gives you the option to save the predicted Leave-one-out error from the model.
