Econ 444, Wednesday September 27, class 3 Review of Monday’s class: Least Squares principle Minimizing n summationdisplay i = 1 ( Y i - ( β 0 + β 1 X i )) 2 over all possible values of β 0 and β 1 gives ˆ β 1 = n · n i = 1 X i Y i - n i = 1 X i · n i = 1 Y i n · n i = 1 X 2 i - ( n i = 1 X i ) 2 and ˆ β 0 = ¯ Y - ˆ β 1 ¯ X . Note ¯ Y = n - 1 n i = 1 Y i , the average of the Y i The mathematical calculation requires being able to find the minimum of a function of two variables using differentiation Robert de Jong Econ 444, Wednesday September 27, class 3

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
