Hey! Your lectures were awesome! Where did you go! The world need more of your videos!
Hey Chris, please upload next videos.. Your teaching style rocks! Life saver.. Please start over
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!
Hi Everyone! We want to know your opinion, comment and let us know how you think we are doing here at Keynes Academy! Subscribe and like if you would like to see more econometrics!
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 :)
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.

He got a A+ paying job is my guess, this stuff is extremely worthwhile to learn. Guessing he's way too busy, cause its a ton of work as you might be able to see from these videos.

I have been struggling to understand conceptually the importance of R^2. This was so helpful!!
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 UA-cam. Nothing ... except for your past few episodes. Bravo!
Man these are some really grate videos. It is a pitty you stopped. You owe it to the world to continue this MAAAAAAN!!!!!!!!!!!!!
You are such a great teacher :)

What's your opinion on that book? I borrowed it from the library but my course focuses more on the econometrics book by Woolridge!
Did you by chance find any substitute video series for that book

hello kris.. your lecture on Regression model really good and understandable.. could you please add any numerical example to find each methods of sum of squares.. and connect real world situation and solution into it..
Can you please continue with the lecture? I really need the continuation of the lectures. you explain the lecture with aplomb!
Waiting for other topics....!!
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 :)
^ Please listen to this man.more videos!
That was easy to understand! Do you perhaps have the sample question regarding on the topic? Do share the link yeah! Looking forward to the next lecture video. :)
