For question #1, only use months April, May and June to calculate MAD.
example
Month | actual | forecast | error |
J | 10 | na | na |
F | 8 | na | na |
M | 9 | na | na |
A | 12 | 11 | 1 |
M | 13 | 9 | 4 |
Ju | 10 | 9 | 1 |
MAD | 2 |
note: for the weighted three-month moving average technique, using the following:
forecast April: 0.2*Jan + 0.3*Feb + 0.5*Mar
forecast May: 0.2*Feb + 0.3*Mar + 0.5*Apr
forecast June: 0.2*Mar + 0.3*Apr + 0.5*May
1d - of the four forecast methods, which one yields the lowest MAD value?
Group of answer choices
3-month moving average
weighted 3-month moving average
linear trend
exponential smoothing
1d - of the four forecast methods, provide the lowest MAD value?
5 - of the three forecast methods, provide the lowest MAD value.
5 - of the three forecast methods, provide the lowest MSE value.
7 - Provide the RSFE value (it's a number) for the forecast method that overproduces forecast sales
