(Ch.7 9) Let d be a dummy (binary) variable and let z be a quantitative variable. Consider the model y = β0 + δ0d + β1z + δ1d∗z + u; this is a general version of a model with an interaction between a dummy variable and a quantitative variable. [An example is in equation (7.17).] (5 pts each) (i) Since it changes nothing important, set the error to zero, u = 0. Then, when d = 0 we can write...
