Problem 3
Consider the following multiple regression model
Y = Bo + B₁X₁i + B2X2i+B3X3i + Ui
You want to consider certain hypotheses involving more than one parameter, and
you know that the regression error is homoskedastic. You decide to test the joint
hypotheses using the homoskedasticity-only F-statistics. For each of the cases below
specify a restricted model and indicate how you would compute the F-statistic to test
for the validity of the restrictions at the 1% level.
1. B₁-B2; B3 = 0
