Time Series Analysis Package

This example uses the TSMODEL procedure to compute the seasonal indices on the time series array Air:

proc tsmodel data=mycas.air outarray=mycas.outarray;
   id date interval=month;
   var air;
   outarrays ADJUSTED;
   require tsa;
   submit;
   declare object TSA(tsa);
   rc=TSA.SEASONALDECOMP(air, _SEASONALITY_, 'ADD', , , , , , , , ADJUSTED, , , );
   endsubmit;
run;
