## Usage

performance_rse(model)

model

A model.

## Value

Numeric, the residual standard error of model.

## Details

The residual standard error is the square root of the residual sum of squares divided by the residual degrees of freedom.

## Examples

data(mtcars)
m <- lm(mpg ~ hp + gear, data = mtcars)
performance_rse(m)
