ols_fpe: Final prediction error

In olsrr: Tools for Building OLS Regression Models

Final prediction error

Description

Estimated mean square error of prediction.

Usage

ols_fpe(model)

Arguments

model

An object of class lm.

Details

Computes the estimated mean square error of prediction for each model selected assuming that the values of the regressors are fixed and that the model is correct.

MSE((n + p) / n)

where MSE = SSE / (n - p), n is the sample size and p is the number of predictors including the intercept

Value

Final prediction error of the model.
