Extrapolation and Forecast 

This was a lifesaver for my IB Math IA, thank you!

Thank you very much Dr. I was struggling to use the TREND functionality to exrapolate for a polynomial equation and that is how i ended up watching this video. Thank a ton !!

Thx!! Right-click on the formula !! I was already ripping my hair out. That was impossible, that function hit y-achsis atz EXACTLY 2,000,000. Thank you soooo much. Now the model works :-)

Thanks Dr. after several attempts using TREND failed, very useful explanation

Nice explanation No doubt salute sir

I finally found a useful video on extrapolation and interpolation! Thanks so much!

Fantastic work Prof.

Thanks Dr Gerard, very well explained

i like the power function using array. thanks for sharing the knowledge regards anand varma

THANK YOU i need this for my thesis

Thanks a lot respected sir! It was really helpful.

Machtig goed uitgelegd Gerard. Thanks a lot !!

Help a lot!! Thank you very much.

Great description, thank you.

Can we use a Gaussian curve to apply to a limited series of data?

thanks Dr Verschuuren !!!

great video.. helped loads...

Oh, and important: Trend works fine but uses a linear model!

Thank you sir 🙏

Does this work if the R2 is not as close as 1? Say 0.7?

Thank you so much Dr

Perfect! Thanks heaps!

Thank you

Thank you, it helped

tq

Nice explanation, but it would be much better to analyze the error due to extrapolation instead of showing all fancy fit.
