Chapter 1 Simple Linear Regression (Part 2)
The fitted regression line/model is Yˆ =1.3931 +0.7874X For any new subject/individual withX, its prediction of E(Y)is Yˆ = b0 +b1X . For the above data, • If X = −3, then we predict Yˆ = −0.9690 • If X = 3, then we predict Yˆ =3.7553 • If X =0.5, then we predict Yˆ =1.7868 2 Properties of Least squares estimators

www.princeton.eduWhen running a regression we are making two assumptions, 1) there is a linear relationship between two variables (i.e. X and Y) and 2) this relationship is additive (i.e. Y= x1 + x2 + …+xN). Technically, linear regression estimates how much Y changes when X changes one unit. In Stata use the command regress, type:
