Ramsey's RESET test for nonlinearity

Adds powers of the fitted values and performs an F-test to check for neglected nonlinearity.

Usage

performRESETTest(model, power = 2:3)

Arguments

model

A fitted lm model.

power

Numeric vector of powers to include.

Value

An object of class htest.

Examples

data(mtcars)
m <- lm(mpg ~ wt + qsec, data = mtcars)
performRESETTest(m)
#> 
#> 	RESET test for nonlinearity
#> 
#> data:  mpg ~ wt + qsec
#> F = 6.7306, df1 = 2, df2 = 27, p-value = 0.00425
