The following data represent total personnel expenses for the Palmdale Human Service Agency for past four fiscal years:
20X1 $5,250,000
20X2 $5,500,000
20X3 $6,000,000
20X4 $6,750,000 Moving Averages
20X2-X4 $18,250,000 / 3 = $6,083,333
Weighted Moving Averages
Fiscal Year Expenses Weight Weighted Score
20X2 $5,500,000 1 $5,500,000
20X3 $6,000,000 2 $12,000,000
20X4 $6,750,000 3 $20,250,000 __ ___________ 6 $37,750,000
20X5 $37,750,000 /6 = $6,291,667
Exponential Smoothing
NF = $6,300,000 + 0.95($6,750,000 - $6,300,000) = $6,300,000 + 0.95(45,000) = $6,300,000 + (42,750) = $6,342,750
I would rather use moving averages, weighted moving averages, or exponential smoothing because I can better understand how the formulas and numbers turn out and how you get the answers from them. Even though the Time regression is supposed to be easier you are still putting a lot of faith in a computer. Plus I really had a hard time understanding it.
