Madame, 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.
Navketan sir, I'm glad that you are learning at this age. Truly you are an inspiration. For double exponential smoothing, please use Holt's and winter model.(double and triple exponential smoothing). The one that I've showcased in the video is simple exponential smoothing. Incase of any doubts, kindly revert. Thanks
For each of the periods, it can be calculated as (forecasted demand -- actual demand) but actual demand for period 7 wasn't mentioned it is hard to say how we do it.
