    Hey! Your lectures were awesome! Where did you go! The world need more of your videos!

    I think your explanations are much better than the tutors that I thought. It's been months and I always thought it'd be so complex for a normal average student to understand but you made it simple and more contextual of the topics. Amazing. Please keep doing videos on these things because it's really helping! Thank you so much!

    These are some really great lectures. Your method of delivery is great. I have never in my life studied these topics and now i somewhat understand them quite better. This tells a lot about how well you have and can deliver. I do not know why did you stop publishing videos but if you can keep on going please do not stop.

      did you just spend 3 lectures to explain least squares for a straight line without even the correct title dummy?

    Hi Chris, hope you are doing well! The world needs more of your videos!!! I learned more from your videos that my professor couldn't teach over 4 months. If you can, please upload some more videos :)

    Thank you Chris for the tutorial videos
    They are of a big help, They explain the topics in a simple and clear way
    I believe you shall have tutorial videos on all topics in econometrics which would be an online education for anyone interested to study econometrics
    You are a hero to the student who doesnt understand from class
    Keep it up and all respect from me

    I just signed up for econometrics after not having taken any math or econ classes for three years, and nothing could get me to understand these (supposedly) simple regression concepts. Not the textbook, not my professor, not other channels on RUclips. Nothing ... except for your past few episodes. Bravo!

    @MehdiElharti 10 лет назад +5

    This was very good. You are a hero :)
    But I looked for lecture 4 and there was none :(
    It would be great if you could do similar presentations on the following:
    1. Multiple Regression
    2. Serial Correlation and how to detect it
    3. Heteroskedasticity and how to detect it
    4. Multicolienarity and to detect it
    5. Forecasting using regression (forecasting error)
    6. Applying regression to time series (stationarity....)
    I personally use gretl for all of my regression work.. it's excellent and free :)

    Important Note: This video uses the notation SSR, SSE and SST for the sum of squared residuals, explained sum of squares, and total sum of squares, respectively. Unfortunately your textbook may use different notation and lots of notations overlap:
    1. The SSR is sometimes denoted as RSS, or less frequently the ESS (for error sum of squares).
    2. The SSE is sometimes denoted as ESS, or less frequently as the RSS (regression sum of squares).
    3. The SST is sometimes denoted as TSS.

    @Tshutshu.M 10 лет назад +1

    Nice Chris. Just one thing SSE is conventionally known to be Sum of Squares Error not Explained. So SSE is the residual deviance from the actual that can not be explained by the model, and SSR is the deviance from the mean, which is explained by the model. Otherwise, great.
