In olsrr: Tools for Building OLS Regression Models

MSEP

Description

Estimated error of prediction, assuming multivariate normality.

Usage

ols_msep(model)

Arguments

model

An object of class lm.

Details

Computes the estimated mean square error of prediction assuming that both independent and dependent variables are multivariate normal.

MSE(n + 1)(n - 2) / n(n - p - 1)

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

Value

Estimated error of prediction of the model.
