Slide 8.3 Undergraduate Econometrics, 2nd Edition-Chapter 8 8.1 The F-Test The F-test for a set of hypotheses is based on a comparison of the sum of squared errors from the original, unrestricted multiple regression model to the sum of squared errors from a regression model in which the null hypothesis is assumed to be true. Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics.It is most often used by scientists to test specific predictions, called hypotheses, that arise from theories.
