WebbRamsey’s RESET test is used to test whether the model is correct or not. This is because our assumption of the appropriate functional form is linear may not always be true. We need residual in order to use the Ramsey’s RESET test.

WebbThe RESET test is a popular diagnostic for correctness of functional form. The basic assumption is that under the alternative the model can be written in the form y = X β + Z γ + u . Z is generated by taking powers either of the fitted response, the regressor variables, or the first principal component of X.
