    Thanks. Very simple and clear explanation.
    You committed a small mistake, in the equation you wrote in green -β₁₂xt and -β₂₁yt, while there should be a plus, such that when you bring them on the left side they get a minus. It did not prevent me to understand the topic, but people may get confused, because if you start with a minus then you should have a plus in the matrix.

      Thank you for making this correction, In the green equation it was intentional so that when we convert it into matrix form we avoid the negative sign. though i forgot it later. Will try to look out for such errors in future. thanks for watching with interest.

      Here is a link to the same video made in urdu where i have used the same negative sign in the start ending with positive matrix.

    Thank you very much for the class, but I have a question about the difference between the VAR Model and cross-lagged in panel data? My question could be so basic and I apologize for that. But I'm really on that and could not find the difference between them. If I understand well, in the second one, the point is about the delta or the change of one in the change of the other variables. In VAR no. The point is not to work using this change.

    Hi thanks so much for the upload. So on 13:31, is it pre multiplication with the inverse or post multiplication with the inverse

    • @economicslectures1
      @economicslectures1  ปีที่แล้ว

      We do not need to multiply it. Just rename the multipication

    i have a one question,
    when you are going L.H.S. to R.H.S then the sign of the variable will be change but here you are not changing sign of beta's

    First of all, I'd like to compliment you for the amazing work. Your didacticism is extremely pleasurable.
    I just have one question that I hope you could answer: I think it must be something basic and trivial at this point, but how did you choose the notations (the underneath numbers) of the beta and gamma coefficients in the equations? Where did they come from?
    (I'm sorry for this so elementary question, but I'm kinda learning by self-taught. By the way, if you could recommend some literature that could clarify questions of these kind, I'd be glad.)
    Thanks!

    • @economicslectures1
      @economicslectures1  3 ปีที่แล้ว

      Thank you so much for such an encouraging response. I am a learner my self but i hope i can provide a satisfactory answer to your question. The underneath numbers do not have a hard and fast rule but they should be numbered/labelled in such a way that you can easily relate to whenever needed. in this case the first number represents whether the order of equation, the second represents the order in which they are written within the equation for a specific coefficient. simply these work as tags for us. in some cases we may use alphabets as well. I havent come across any literature for learning these notations but have learned it this way in class my self when i was studying econometrics. But i can recommend books that are easy to understand. I have found 'Introduction to Econometrics' by Stock and Watson The most easy book to learn from. Applied Econometrics by Demetrious Asterio is easy if you are interested in Eviews etc.
      Good Luck!

    Sir I want to apply var model on death injury and accident variables but I am confused that how can I interpret because death is not cause of death

    • @mudassirgaur6705

      Saima you cant aply VAR model in this case .use AR or Panel model .

  • @JJ-fb2lp

    I think what you shown here is Structural VAR model.

    At time 8:23 why the negative sign is not changed when negative value is moved to left hand side??

    • @economicslectures1
      @economicslectures1  2 ปีที่แล้ว

      Yes you are right, the sign should change when we move it to the left hand side, it is a mistake on my side. Infact, we are using the negative sign in first place at 3:33 so that once we move it to LHS we have positive value. Thanks for the correction

      thank you for your feedback, I do not fully understand your comment, I have used one note and screen recording for this lecture, But i am still learning to improve video making skills. Thanks for watching.
