Getting MAE from Holt-Winters
Posted: Thu Apr 22, 2010 9:55 pm
When I run Holt-Winters Additive & Multiplicative Seasonality tests, I get a Sum of Squared Residuals and a Root Mean Squared Error.
However, I need to get a MAE. How can I manipulate the data to get this? Also, my residuals did not store. For some reason, it says NA, even after I run the tests.
Thanks again for all your help.
