Amemiya's prediction error of the model.

Amemiya's Prediction Criterion penalizes R-squared more heavily than does adjusted R-squared for each addition degree of freedom used on the right-hand-side of the equation. The lower the better for this criterion.

$$((n + p) / (n - p))(1 - (R^2))$$

where *n* is the sample size, *p* is the number of predictors including the intercept and
*R^2* is the coefficient of determination.
