Cаmpаign Expenditure (pаrt 4) Use the VOTE.DTA data fоr this questiоn. Cоnsider the following model voteA=β0+β1ln(expendA)+β2ln(expendB)+β3prtystrA+u{"version":"1.1","math":"voteA = beta_0 + beta_1 ln(expendA) + beta_2 ln(expendB) + beta_3 prtystrA + u"} where voteA is the percentage of the vote received by candidate A, expendA and expendB are the campaign expenditures by candidates A and B respectively, and prtystrA is the percentage of the most recent presidential vote that went to A's party. Now re-parameterize the model to test the null hypothesis from the previous question, i.e., a 1% increase in candidate A's expenditure would be exactly offset by a 1% increase in candidate B's expenditure. Let θ=β1+β2{"version":"1.1","math":"θ=β1+β2"} The null hypothesis will be:
