PROC X12 for seasonal adjustment

[ankush2301]

Hi All,

I am trying to decompose my time series data into trend and seasonality and using proc X12 for this in SAS VIYA3.4. After executing the following code i am facing error msg :-

NOTE: This release of the X13 procedure is based on the Census Bureau X-13ARIMA-SEATS Release Version 1.1.

ERROR: Invalid values : INTERVAL=WEEK1. .

proc x12 data=sales_data date=date;
var sales_qty;
transform power=0;
arima model=( (0,1,1)(0,1,1) );
estimate;
x11;
run;

I have already tried giving interval = week as well, but it doesnt work. Any help will be appreciated

Thanks

Ankush

The Census Bureau X12 method only supports monthly and quarterly data.
