Usage resettest (formula, power = 2:3, type = c ("fitted", "regressor", "princomp"), data = list (), vcov = NULL, …) Arguments formula a symbolic description for the model to be tested (or … 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. A standard F-Test is then applied ...
