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.

The answer to this is not as straightforward as you would like. It depends on the software and the code you write with it.

Thank you so much, now I wonder how can we use these data, calculation to improve the forecast ?

[@dr.damikabiawu4976]

The error calculations can be used as a feedback mechanism. It tells when your actual starts to depart from your forecasts.

Hello Dami, very good explanation. Why you use n-1 instead of n when you calculate MSE? is it MSE formula = (1/n) * Σ(actual - forecast)^2 ?
