2a) Let income denote the person's income and age denote the persons age. We would like to run an OLS regression on the equation BMI=B0+B1fast+B2income+B3age+U. Write down all the assumptions that guarantee that the OLS estimators of the coefficients of this equation are unbiased correct answers 1)Linearity- E[U|fast, income, age]=0, The expected value of y is linear in X1,X2,X3 2)Exogeneity- E[U|fast, income, age]=0, unobservables are constant and do not effect BMI 3)Random Sampling- The dat...
