250,000 20X5 $6,300,000 6=$37,750,000 For 20X5 I divided by 6 (which represents the values 1+2+3=6), which equals $6,291,667 or $6,300,000 as a weighted average. From the information gathered a prediction for the forecast can be made. Exponential smoothing: The alpha method of 0.95 would work here. The formula would look like this: NF=LF + a (LD- LF) Last Forecast (LF) = $6,300,000 Last Data (LD) = $6,750,000 a = 0.9 NF = LF + (LD LF) NF = 6,300,000 + 0.95(6,750,000 - 6,300,000) NF=6,300...

SMOOTHING TECHNIQUES Several techniques are available to forecast time-series data that are stationary or that include no significant trend, cyclical, or seasonal effects. These techniques are often referred to as smoothing techniques because they produce forecasts based on “smoothing out” the irregular fluctuation effects in the time-series data. Three general categories of smoothing techniques are presented here: • Naive forecasting models are simple models in which it is assumed that the...
