Simple Linear Regression: A Full Example (Old, fast version)

I work through an example relating eggshell thickness to DDT concentration, fitting the least squares line, using the line for prediction, interpreting the coefficient of determination, checking the residual plots and carrying out a test on the slope.

The data used is from:
Risebrough, R. (1972). Effects of environmental pollutants upon animals other than man. In Proceedings of the Sixth Berkeley Symposium on Mathematical Statistics and Probability.

You're welcome! I've slowed down a touch in my more recent videos, but I still very much try to be clear and concise. I'm glad you found this one helpful.

Thanks for the feedback. I may very well do some R tutorials in the future.

You are very welcome. I'll most definitely keep it up -- I'll be uploading some new videos in the near future. I'm very glad you find my videos helpful.

Thanks for the feedback. I'm glad you find them useful!

You are an awesome teacher. I really appreciate your teaching style and your enthusiasm for the subject. I'm doing really well in my Business stats II class and with all the help I'm getting from your videos, I look forward with confidence that I'll do well when I take my Econometrics course in the fall. Thank you so very much. Keep up the excellent work you're doing.

Great to hear, in either case I shared this with some classmates who have trouble with the fundamentals of statistics, particularly interpreting them through R. Thanks a million!

I thought this sounded like my old stats prof....then to my surprise it was! Great job Dr. Balka

[MrAntihumanism]

you should make tutorials for R - you'll get thousands of views. I am at harvard, and nothing has ever been done like this. Well done.

Thanks! I hope you learned something (in the course and the video)!

Thanks for the feedback. I may very well do some R tutorials in the future.
