For example: y = 0 + 1 * x1 + u is valid, while y = 1 + 1^2 * x1 + u is not, because the coefficient 1^2 is not linear. Add another independent variable to the model. var pid = 'ca-pub-5928451080551316'; But is this the same across values of each independent variable, such that: E(u|educ=20)=E(u|educ=3)=E(u|ability=10)=E(u|ability=1) ?.
