Exponential Smoothing in Forecasting

[@joebeck0]

I just want to say thank you for all of your videos regarding operations management. I am a senior at Siena College in Loudonville, NY and my professor has a very thick accent from South Korea and some of the information is hard to understand. Your videos and review have been a life saver to my learning throughout the semester. Happy holidays.

you helped me a lot… thank you so much!

And how does it forecast the first forecast of the sequence?

[@mikevonmassow687]

You can pick a starting point arbitrarily using naive, moving average, or other approach.

Hi, how did you get a forecast of 20.3 for the 6th week?

Thank you so much I have one question how to a form product dd for the least period is given below period dd period 1,2,3,4,5,6,7,8,9 dd 44,52,50,54,55,55,60,56,62 develop a linear trend equation ,predict the dd value for the next period and find the regression equation solution can you help me please

Hello Mike. Thanks for your videos, they've helped me alot. I have not seen you make a video about double exponential smoothing. Do you know how to set the initial values St and Tt? I have a test for this in little over a week. The question can look similar to this: Week 1, Sales 153 Week 2, Sales 172 Week 3, Sales 181 Week 4, Sales 195 Forecast week 5 by using double exponential smoothing (Holt's method) with α= 0.3 & β= 0.3. This is the information I have to work with. Obviously the three formulas will be: St = αyt + (1 − α)(St−1 + Tt−1) Tt = β(St − St−1) + (1 − β)Tt−1 & ŷt+h = St + h ∙ Tt First you have to do St and Tt for week 1, but how do you make the initial values for week 1, or for the first time period? If there is anyone who know, I would be very glad if you could help by replying to this comment. Cheers. //Oh and btw. There is a formula in my book which follows = T0= y5-y1/4 & S0= y1+y2+y3+y4+y5/5 - 3T0. But it seems like you need 5 time periods or more to use this formula? How to when you have 4 or less and is the formula the correct one for 5 or more?

there is a plan for that video
