    Ben, I know you have been told it a million times, but I can't emphasise enough how grateful I am for these very didactic videos! God bless

      Is it not usually the case that an increase in mathematic knowledge is associated with a decrease in beliefs in God?

      @Kyrie Kody Thanks so much for your reply. I got to the site through google and Im in the hacking process atm.
      Takes quite some time so I will get back to you later with my results.

    I was so caught up watching your "full course" that I didn't realize you were now uploading stuff for panel data. Once again, you'll be my best friend this semester. Big thanks!

      I'm already looking at a couple of online (text) tutorials on time series decomposition, but it would be great to hear your approach on that subject.

    • @SpartacanUsuals

      Hi, thanks for your message. If you could be more specific about time series decomposition that would be great - I can then add this topic to my list of things I intend to cover. Again, thanks for your input here! Best, Ben

    Brilliant! and I don't mean it in the way the Brits do (cool) - I mean it in the way Americans do(very smart). I have been studying FE/FD models for a few weeks and I have not seen a more intuitive snapshot than this.

    Hi Ben, wanted to thank you for your videos and especially this simple diagram showing intuition behind how pooled ols and FE give different correlations. Helped hugely with dissertation ! Owe a lot to your videos. Thanks.

    What an excellent video, just what I was looking for. A simple and quick, but still highly comprehensible overview of FE vs OLS. It was also fairly topical considering I'm from Brighton, thanks!

    Thank you so much Sir for these lecture series! Explained so well, I like and watch your lectures a lot!
    Sir, is there any theory- based assignment also to practice questions based on panel data (as is available in case of time series). If yes, then kindly share the link🙏

    So first differences isn’t like a derivative wipes the constant or fixed effects.The constant term is gone but you are saying that take time unchanging similar properties for all of three cities?

  • @sunnyboy288
    @sunnyboy288 6 лет назад

    Can you please clarify what you say at 6:04? Line through the center of average of all the observations or just the Bristol city's average? "And the line should pass close to other two observations" . Should it pass closest to two observations of only Bristol city? or the two observations of all the cities?

    Hi Ben, I just started watching your lectures on RUclips since last years, and I really enjoy watching all of it. It's been really helpful for me to improve my understanding on econometrics and related topics, as I am doing my graduate study. Related to this video, is it possible to show how the line in the graph looks like if we estimate the effect of unemployment on crime rate with Random Effects? Thanks!

  • @martineuwe4144
    @martineuwe4144 8 лет назад

    Very helpfull, thanks! But I still have a question.. So in this example what is the difference between year fixed effects and say city fixed effect? Or is this just terminology?

    Hi, Great Vids, If you had the results from a panel model: RENTt = 1.7 + 2.6GDPt - 1.3SIR t-2
    How would you go about answering how to calculate fixed affects in the above model?
    Thanks

    Your thesis is that the crime rate only depends on the unemployment rate. There could be other factors. Maybe the population became more religious which has much more influence to decrease the crime rate.

    When you spend 50k on tuition fees for a "good" university and you end up learning what you need because you're university didn't teach it to you for free on youtube. Such jokes, and tks Benny
