Think about our game plan discussion from class this week. Suppose we conduct a global F-test and reject Ho. Suppose we test for quadratics and FTR Ho and test for Interaction and Reject Ho. Which model would you say is the "best" model at this point in our testing? Model 1: E(y) Model 2: E (y) Model 3: E(y) Model 4: E (y) Bo + B121 + B22; + B322 + B42122 + B5 21 22 Bo + B121 + B322 + 342122 Bo + B121 + B22? + B302 Bo + B121 + B3x2 Model 4 O Model 1 O Model 3 Model 2
