a)
Explain the calculation method for the Naive Forecast model.
If at the end of every month from January/2019 to December/2019, the Sales Manager
would have applied the Naive Model, calculate the Naive Forecast values for the months of
Febru/2019 and all the way to January/2020. Enter those values on the table above.
b)
c)
Calculate the Absolute Value of Error for every forecasted month, from February/2019 to
December/2020. Enter those values on the table above.
- Why are there months when the Absolute Value of Error is very low and months when it is
gher?
- Calculate the Mean Absolute Deviation (MAD), the Mean Squared Error (MSE) and the
ean Absolute Percent Error (MAPE) for the Naive Forecast you created for Product X from
March/2019 to December/2020 (not from February/2019 to January/2020).
