    I can't put my finger on how you do it, but you manage to explain so many concepts so clearly and concisely. I learned more in twenty minutes from than in a two hour lecture hall. Fantastic!

      I would like to know, if we have the total revenue and total debt, which should be considered as the independent variable and which as the dependent one, as well as if we have the price per share and the volume of the traded shares. Which of these have to be applied as y and which as x?
      Thank you.

    • @BrandonFoltz
      @BrandonFoltz  10 лет назад +1

      + Lozan Lishev What is your research question? What are you attempting to predict/determine? That will determine the model structure.

    • @electrolish5193
      @electrolish5193 10 лет назад +2

      In the former case I am trying to predict the revenue about the upcoming year, and in the latter case I am trying to understand how the volume of traded shares is impacting on the price.
      Thank you.

    • @BrandonFoltz
      @BrandonFoltz  10 лет назад +2

      OK. In the first case the revenue is the dependent variable (y) and total debt would be the independent (x). In the second case price is the dependent. The dependent (y) variable is what you are trying to predict.

    • @electrolish5193
      @electrolish5193 10 лет назад

      Yes I just saw your videos regarding correlation and many things have become clear to me. I am just new to statistics, I have tried to study math as a subject, just to know how to calculate, but later on I realized that the world has its own math incarnated in time’s dimensions. Anyhow, in my opinion is very important to pick up our data and prediction selectively, because nonlinearity and uncertainty appear more often, than we think.
      Thank you.

    Wonderful. I've not heard of 'dummy' variables before. This video is close to what I think I need to do for some of my analysis. I have 4 categories of wetlands that I ranked based on landuse in a 100m buffer around the wetland. What I'm trying to see is if that LU rank can predict the way the wetland scores on an ecological assessment. Cool. Though I'm a long way from understanding all of this, I'm no longer buried under the mud. This stuff is actually pretty cool. Love what you're doing and how you go about presenting the lessons.

      Hey Brandon, got a 100 in my multiple regression test today!! Thank you for your work. One quick question that I have been having a difficult time in getting answered correctly. When using a T-table or any stats table for that matter and the degrees of freedom that you need is not listed which value do you use?
      For example:
      I need to look up 65 degrees of freedom but the table only lists 60 then skips right to 70. Which critical value should I use?

    Thanks Brandon, in very simple way you have really clarified a number of misconceptions of mine which many people had created in me about regression while teaching me regression. I've just watched this 4th lecture and these lectures have boosted my moral to write some article using regression. One of my professors said that these days regression technique is obsolete and is not that reliable, it is taught to students just for the sake of basic learning. What are your comments?

  • @jonathanweininger7857
    @jonathanweininger7857 3 года назад

    Great explanation. Thanks for putting together such clear content. There appear to be two significant outliers, one in each group (exemplary and not); maybe foreclosures? Those data points are pulling down the slope. With more data and some light outlier detection and removal, this likely wouldn't be an issue. Wondering if others think about this similarly.

    I want to let you know at 17:46 on the presentation you have the wrong coef number for beta one.
    E(y|exemplary) = (27.1 +98.6) + **98.6x1** ---> 0.0621x1

    I think it actually could be reasonable to exclude the bottom blue point (2000 sqft to 50 price) as an outlier as it's too far away from the other points, which generally seem to form a better linear relationship. In that case we'd get a much better fit for the blue points.
