What is Forecasting ?
Forecasting is a very useful future analysis technique for demand and sales data for different units and processes. This method is used to estimate future sales and demand. It is also useful in trend analysis to evaluate future trends and forecasting.
The formula to compute three-month moving average MA(3) to forecast sales for the [tex]n^{th}[/tex] period is shown below:
[tex]Forecastperiod(n)[/tex] [tex]=[/tex] [tex]\frac{Y_{n-3} + Y_{n- 2} + Y_{n- 1}}{3}[/tex]
July = [tex]\frac{435 + 465 + 315 }{3} \\[/tex]
July = [tex]\frac{1,215}{3}[/tex]
July = 405
Thus , the forecasted sales for July is 405.
