More specifically, it tests whether non-linear combinations of the fitted values help explain the response variable. Webb7. Ramsey’s RESET test is a test of whether the functional form of the regression is appropriate. In other words, we test whether the relationship between the dependent variable and the independent variables really should be linear or whether a non-linear form would be more appropriate. short stories of the harlem renaissance

Therefore, it is useful to test the significance of signals before moving onto further analyses such as DLMs and the ARDL bounds testing.
