I have a question which is an extension of the topic discussed in this video. I understand how to estimate the 95% Confidence Interval and 95% Prediction Interval for linear regression. Could you please guide me to any discussions where these quantities are estimated for non-linear regression? Thank you.
This is regressión of polynomial curves?, or we are just finding a parabolic tendency line... Is this Useful if i want to use Multi Factos like X,z,W, not only to determine Y
This is much more helpful. Thanks Tom!
This video was extremely helpful. It explained the basics of a polynomial regression very clearly, Thank you!
Very helpful. Thank you very much.
Thanks. I taught statistics in a Chinese University 15 years ago. I wish a video such as this had been available then.
This was extremely helpful! Thank you! On top of the regression data I now know how the graphs work. One million thanks
Really really helpful and very clear explanation.Thanks. For Mathematics' knowledge NO AGE> God bless
Thanks guy ! That's the solution i was looking for !
Presentation is excellent and also the example marvelous
Also works for excel2007 ... THANKS A LOT!
thanks! this is precisely what i needed.
Thanks for this!! it was really useful!
Hello Tom,
Great video.
R-squared is coefficient of determination, expected value is between 0 to 1 and not -1 to 1
Thank you! Needed this for uni

At 3:00-3:15 minute mark: r^2 is between 0 and 1 because r is between -1 and 1.
how to get the coefficients in a cell rather than in an equation within the chart?
great video. Can you please explain how to get the variables out of the equation for use elsewhere in excel?
Great video! I am having a little difficulty in fitting a 7th order polynomial or higher in excel. Does it only fit up to 6th order polynomial ?
yes, no more than 6
Thanks!!!
Maybe just copy and paste the graphs next time? :)
