Dependent variable ( sales qty) has very low values and vary between value of 0 to 40 with lot of variation.</P><P>S_level from this model is a line which is like an average and cuts across the middle of the dependent series. I was expecting that s_level without any variance control would actually fit the model well but that's is not the case.</P><P>Can you please help me in understanding what might be happening here and what option I could try such that s_level fits that model well?</P><P></P><P>Apologies if my query is unclear or some additional information is needed.</P><P></P><P>Thanks,</P><P>Mayank</P></BODY></HTML> Sat, 17 Aug 2013 08:18:14 GMT https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/UCM-modelling/m-p/113847#M624 MayankAhuja 2013-08-17T08:18:14Z Re: UCM modelling https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/UCM-modelling/m-p/113848#M625 <HTML><HEAD></HEAD><BODY><P>Hi Mayank,</P><P></P><P>Thanks for the question.&nbsp; Would you mind sharing some code for what you are doing?&nbsp; Perhaps a graph of the series or some background on the type of units?</P><P></P><P>There are a number of simple examples at <A href="http://support.sas.com/documentation/cdl/en/etsug/65545/HTML/default/viewer.htm#etsug_ucm_gettingstarted01.htm" title="http://support.sas.com/documentation/cdl/en/etsug/65545/HTML/default/viewer.htm#etsug_ucm_gettingstarted01.htm">SAS/ETS(R) 12.1 User's Guide</A></P><P>which could help to get you started.</P><P>Thanks</P></BODY></HTML> Mon, 19 Aug 2013 17:34:05 GMT https://communities.sas.com/t5/SAS-Forecasting-and-Econometrics/UCM-modelling/m-p/113848#M625 ets_kps 2013-08-19T17:34:05Z
