Can someone provide a syntax that test high frequency seasonal time series for stationarity (seasonal length is 52 weeks).

Hello -

Not sure if this paper provides you with what you are looking for: http://analytics.ncsu.edu/sesug/2010/SDA12.Dickey.pdf, but it might point you in the correct direction.

Thanks,

And this 2009 SGF presentation Simulating Time Series Testing Using SAS® - Part I The Augmented Dickey-Fuller (ADF) Test appears to have an explicit stationarity test, with SAS code.

The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets
