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.

How do we get 0.3

WTF really thank you...

@MyMy-tv7fd 2 жыл бұрын

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?

THIS GUY IS WRITING BACKWORDS. TURTLE. HERM HERM HERM

no he is standing behind a glass board so he is wrinting normal.

@nannybannany 11 жыл бұрын

lol maybe so Daniel but it's more likely that it's just a mirror image.

@wHisperis001 11 жыл бұрын

He's not writing backwards, the video was simply flipped

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.
