Demand for Month Bulldozers ЗМА Error 4MA Error 1 8 12 4 9. 15 11 10 8. 12 9? AE AE a) Compute three-month moving average for months 4-9 and four-month moving average for mont 5-9. Úse at least one decimal place: so your forecast should be 10.3, etc. b) Compute the errors for each forecast (note: can't do this for month 9), and (at the bottom) the Average Error for only months 5-8 for each. (Note: it's important to compare the two forecasts evenly).

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
