Description

Amemiya's prediction error.

Usage

Arguments

Details

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 higher 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.

Value

Amemiya's prediction error of the model.
