Considerthemultiplelinearregressionmodel,y = 0 + 1x1 + 2x2 + 3x3 + . You wish to test

Considerthemultiplelinearregressionmodel,y = β0 + β1x1 +

β 2x2 + β3x3 + ε . You wish to test whether the slope coefficients

β1 and β3 are jointly significant. Define the restricted and the unrestricted models needed to conduct the test.
