    Thank you so much for these brilliant videos. I am now taking econometrics 2(panel data) but I didn't have the proper foundation from the first course since I was a bit too lazy at the time. Going through econometrics 1 and 2 at the same time is a bit of a mouthful but these videos are a great help. Concise and the many short videos somehow seem less daunting than sitting through a 2 hour lecture.

    I've been preparing for an exam this whole week, and watching your videos is really helpful! Especially to understand why something is done this or that way which is actually the most important question! So thanks :)
    I wish my professor was like that...

    Oh God, thank you so much! I have had so much trouble figuring out what "constant variance of error" actually mean - your explanation was CLEAR and i mean CLEAR - this is after reading several econometrics textbooks!!!

    Thank you so much! I was looking for the G-M assumptions so far and finally got it! really appreciate your video.

    Thank you, this explanation of homoskedasticity was really helpful!

    Hello Porfessor, I have a question: Cov(ui,uj)=0 doesn't mean that ui and uj are independent. At the end of the video, why did you say that they are essentially independent?

      Hear, hear.
      He may have had in mind another assumption, used later on for hypothesis testing, which requires {ui} to be jointly normally distributed.

    Thank you very much, dear teacher
    I have a question
    If we have more than two independent variables in this case, how can I find the significance test for the estimated parameters?

    I don't get how we can make the homoskedastic assumption in practice, how could the variance of error be always the same..

    • @ruchiyadav3633
      @ruchiyadav3633 7 ปีที่แล้ว +1

      it is not necessary
      but as we know the regression line goes through the best possible lace minimising the disturbance terms which means homoscedasity can occur
