9 month moving average
Ft+1 = α ∙ Dt + α(1 − α) ∙ Dt−1 + α(1 − α)2 ∙ Dt−2 + α(1 − α)3 ∙ Dt−3 + α(1 − α)4 ∙ Dt−4 + α(1 − α)5 ∙ Dt−5 + α(1 − α)6 ∙ Dt−6 + α(1 − α)7 ∙ Dt−7 + α(1 − α)8 ∙ Dt−8
Ft+1 = 0.2 × 73 + 0.2(1 − 0.2) ∙ 60 + 0.2 (1 − 0.2)2 ∙ 84+ 0.2(1 − 0.2)3 ∙ 101+ 0.2(1 − 0.2)4 ∙ 80+ 0.2(1 − 0.2)5 ∙ 71+ 0.2(1 − 0.2)6 ∙ 90+ 0.2(1 − 0.2)7 ∙ 65+ 0.2(1 − 0.2)8 ∙ 78
= 66.56
