My problem is when I specidy the lag 12 of moving average the estimation failed, a ridge was encountred in the objective function, things can happened.<BR /> But the estimation has no problem to estimate with an lag 24 (without 12) of moving average whereas lag 12 and lag 24 are correlated!!<BR /> <BR /> Thanks<BR /> NJ Fri, 06 May 2011 12:41:17 GMT https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/Times-Series-using-Enterprise-guide-problem/m-p/62924#M287 NJ 2011-05-06T12:41:17Z Re: Times Series using Enterprise guide: problem https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/Times-Series-using-Enterprise-guide-problem/m-p/62925#M288 <HTML><HEAD></HEAD><BODY><P><BR />We are having this same problem using HPF.&nbsp; Did you resolve it?</P></BODY></HTML> Tue, 02 Apr 2013 21:52:28 GMT https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/Times-Series-using-Enterprise-guide-problem/m-p/62925#M288 mbrahm 2013-04-02T21:52:28Z Re: Times Series using Enterprise guide: problem https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/Times-Series-using-Enterprise-guide-problem/m-p/62926#M289 <HTML><HEAD></HEAD><BODY><P>Hello -</P><P>Can you share some more details on the problem you are facing with HPF?</P><P>Ideally sharing a code example and test data for illustration purposes...</P><P>Thanks,</P><P>Udo</P></BODY></HTML> Wed, 03 Apr 2013 12:43:36 GMT https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/Times-Series-using-Enterprise-guide-problem/m-p/62926#M289 udo_sas 2013-04-03T12:43:36Z
