https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/SAS-Forecasting-Modeling/m-p/39594#M165 Hi Russ,<BR /> Best to my knowledge it might be fair to state that MAPE is the most popular forecasting statistic. This does not imply that it is the best one to use. In fact there are many know limitations to MAPE - for example if the actual values are 0.<BR /> <BR /> May I refer you to "Another look at measures of forecast accuracy" by Rob J. Hyndman andAnne B. Koehler for a detailed discussed and comparison of different forecasting accuracy statistics.<BR /> The paper can be accessed at: <A href="http://www.robjhyndman.com/index.php?option=com_content&amp;task=view&amp;id=280&amp;Itemid=69" target="_blank">http://www.robjhyndman.com/index.php?option=com_content&amp;task=view&amp;id=280&amp;Itemid=69</A><BR /> <BR /> Regards,<BR /> Udo Fri, 26 Sep 2008 15:17:45 GMT udo_sas 2008-09-26T15:17:45Z https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/SAS-Forecasting-Modeling/m-p/39592#M163 Hi,<BR /> May i know the detailed concept of Accuracy in forecasting?. And how is it used?.<BR /> Thanks,<BR /> Russ Sun, 17 Aug 2008 13:44:08 GMT https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/SAS-Forecasting-Modeling/m-p/39592#M163 deleted_user 2008-08-17T13:44:08Z https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/SAS-Forecasting-Modeling/m-p/39593#M164 Sir,<BR /> May i know Why is the MAPE is best?.<BR /> Thanks,<BR /> Rus Sat, 30 Aug 2008 03:23:52 GMT https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/SAS-Forecasting-Modeling/m-p/39593#M164 deleted_user 2008-08-30T03:23:52Z https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/SAS-Forecasting-Modeling/m-p/39594#M165 Hi Russ,<BR /> Best to my knowledge it might be fair to state that MAPE is the most popular forecasting statistic.
