The regression equation below is predicting a person’s hourly earnings (wage) using years of education (educ), years of experience (exper), and two dummy variables. The dummy variable married equals 1 if the person is married and 0 if otherwise. The dummy variable metro equals 1 if the person lives in a metro area and 0 if otherwise.
