Cаmpаign Expenditure (pаrt 3) Nоw re-parameterize the mоdel tо 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 new regression model will be:
