CHAPTER 5 Multiple Regression Analysis: OLS Asymptotics 165 Why cannot Assumption MLR.6 hold for the error term u? What consequences does this have for using the usual t statistic to test H0: b3 5 0? (c) Estimate the model from part (b) and obtain the t statistic and associated p-value for testing H0: b3 5 0. How would you defend your findings to someone who makes the following statement: You cannot trust that p-value because clearly the error term in the equation cannot have a normal distribution.
