Is there a way to forecast next year's sales for each of these zip codes?<BR /> <BR /> I know how to use PROC ARIMA to do one zip code at a time but is there a way to do them all at once?<BR /> <BR /> Thanks,<BR /> <BR /> -MBI Mon, 28 Dec 2009 17:49:44 GMT MBI 2009-12-28T17:49:44Z https://communities.sas.com/t5/SAS-Procedures/PROC-ARIMA-for-multiple-zip-codes-in-one-step/m-p/35086#M8602 Hello,<BR /> <BR /> I have annual sales data from 2001 to 2009 for several hundred zip codes.
