Re: SYS21 - SKEP Forecasting

["Greg Wieczorek" <wieczog@xxxxxxxxxxxx>]

Another reason for switching is the limited number of forecast methods and a
total lack of any method that handles discontinuous demand history well. I
also would suggest that whatever forecasting software a member of the list
select, that they verify that more than 1 measure of statistical error be
supported. When I found that the S21 forecasting solution only calculated
the MAPE and not the MAD, tracking signal, or standard deviation I was
disappointed.
