    This was a very clear way of explaining it! I pay thousands of dollars for professors to ignore my requests for help and could not care less if their students pass or not. You're a great teacher, unlike everyone at Krannert Management School of Purdue U. Thank you!!!!

      I never thought that I would come to understand derivation of estimates easier like this

    Nice and wonderful content. I would be very happy if you can calculate the coefficient in case of TLS or total least square method too

    Can you please show one more thing of this calculation. Like how we can obtain intercept and slope of B0 and B1 after shifting line l to l'?

    This video is so helpful and clearly explained. Thank you so much!
    But Please does anyone know why alpha hat a^ (which is not indexed by i) is in the summation but beta hat B^ gets taken out ?

      Since it's a partial derivative with respect to â, b hat is held constant and can therefore be pulled out of the sigma.

      @@louie30003000 do you know why we put a focus with the partial derivative on alpha?

    • @louie30003000
      @louie30003000 หลายเดือนก่อน

      @@hassanbolagligsmanSince the regression line y=a^ + b^x has two unknowns (the y-intercept a^ and the slope b^), to minimize the residual square function requires taking two partial derivatives: first with respect to a^ (where b^ is considered a constant), and then with respect to b^(where a^ is considered a constant).

    @aslay1064 2 ปีที่แล้ว

    if you divide the first derivative by 2, should the answer be (yi-a^-b^xi)/2 = 0
    You just casually got rid of the 2 and the minus sign??

    Sir, great video. I need a little help, I have a question which I'm not understanding properly. Can you make a video of it to explain it to us. I can share the question to you, if you provide me your email address. It will be really helpful. Thanks in advance
