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

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.

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 ?

Thanks mam

I love it 🥰 ,But how we can display it on a chart?
