1.11 Time Series- exponential smoothing. Part of the Maths Doctor A level video help series. www.mathsdoctor.tv - Maths Doctor provide one-to-one live online tutoring.
useful, but the procedure is plainly misnamed - there are no exponents involved. And what applications would this procedure be useful for? No-one analyses random strings of numbers in this way - what time series is it typically used on?
Sir, If I am doing double exponential smoothing 5 period moving average with a software program-after 5 period exponential moving average is calculated say (X) does computer do second calculation with data X and (X-t1) (X-t2) (X-t3) (X-t4) - - - forgive me,I went to college 50 years ago..(X-t1) is exponential moving average one period prior & so on.Thank you.
I'm more impressed on how he can write so well backwards.
Also helped thank you
its recorded with a special camera. he writes it normal but its projected mirrored
@@babyyoda1968 yeah. i noticed he has his ring on on the "right hand"
We need instructors like these in our university UTEP. It helped me alot!! Thanks yall!
Wow. Writing backwards AND clear teaching instructions. Yep, this vid has my thumbs up vote!
you have saved my life Mr Maths Doctor TV. Thank you for uploading the video
Thank you, this really helped me in my Operations Managment Class. I liked how the board is see-threw. Very cool. Again thanks
Very well-demostrated. Thank you!
Thank you for taking the time to do this video. It was very informative.
Yes this great I'll be ready for my Operations management mid term today
thanks a lot, i really enjoyed your simple way of delivering a knowledge and guess what is is free.Appreciate it
This was really helpful. Thank you!!!
Thank you!
very nicely explained
super helpful. thank you

Thanks alot, sir
excellent explanation .. Thank you :-D
How do we get 0.3
What sort of marker pen did he use?
very useful, ty
how did you pick 0.3 for the alpha value?
Always given
I still don't get how did the 0.3 value came for alpha
Always given
He means it's a mirror image. I'm not sure it's even possible to do a 180° flip like what you've suggested.
no he is standing behind a glass board so he is wrinting normal.
He's not writing backwards, the video was simply flipped
lol maybe so Daniel but it's more likely that it's just a mirror image.
THIS GUY IS WRITING BACKWORDS. TURTLE. HERM HERM HERM

WTF really thank you...
It is better to wear black t-shirt and trousers
maybe he is just jewish, hebrew is written from right to left lol
