Hi Everyone, I have a very simple data set I am trying to deseasonalize. The data is quarterly. There are two columns in the data set. Imported from excel, Column 1 is Period, and Column Two is Total Taxes. Those dates repeat all the way to 2016. 1 03/31/1994 7823982 2 06/30/1994 9398529 3 09/30/1994 8126101 4 12/31/1994 7962473 I found this generic Proc X11 code online: proc x11 data=dataset; monthly date=date;/*needs to be in date9. format*/ tables d10 d11 d12 d13; output out=output_dataset b1=originald10=seasonald11=adjustedd12=trendd13=irreg; var variable;/*variable is the variable to be analysed*/ run; But the thing is my dates need to be converted to a date9. format & the code needs to be adjusted for quarterly data, not monthly. I really appreciate any help I can get with this. I am a bit of a noob. Thanks, Saieed.
