Hello,
I am trying to do a seasonal adjustment on a data set using procX12. My error is as follows:
ERROR: Interval of date variable does not match INTERVAL=YEAR
The data set is an excel document that was properly imported (I know this because I have made a time series plot with the data).
The year is a 4 digit year such as 1999.
My code is as follows:
data seasonlogsun;
set logsunspots;
date=year;
format date Year;
run;
proc x12 data=seasonlogsun date=date interval=year;
var logsun;
x11;
ods select d11;
run;
Any help would be greatly appreciated.
