Hello, I'm doing simulations on detecting seasonality using proc x12 statement, i want to get Fs stat that is behind D8A#1 output. All the stats provided are very nice, but I need to get many, many, I mean many Fs stats. It actually takes too long for proc x12 statement to give me the results, so I wonder if it is possible to get SAS running only on Fs stats and not loosing time in all other tables calculation : it needs only table B1, B2 and B3 to get Fs. Any suggestions other than to code manually the process to get my results faster? Because it is already done, but I want as fast as possible, I'm more statistician than programmer 😞 That's the basic code for PROC X12 provided as exemple from SAS support. ods output D8A#1=SalesD8A_1;
ods output D8A#2=SalesD8A_2;
ods output D8A#3=SalesD8A_3;
ods output D8A#4=SalesD8A_4;
proc x12 data=sales date=date;
var sales;
transform power=0;
arima model=( (0,1,1)(0,1,1) );
estimate;
x11;
run; Also, on the side, another little question : Stat M7 is : sqrt(0.5* (7/Fs + 3*Fm/Fs) ) Is someone knows where the 7 come from? Is it the same 7 as general critical value to reject H0 for Fs that is many times used? We also want 7/Fs smaller than 1 to detect present combined seasonality, that's what's making me thinking that way. Any information on that 7 will be very welcome!! Thank you all, and happy coding! Marc Ps : sorry for my english ahah not perfect!
