Time Series Analysis Package

This example uses the TSMODEL procedure to take the log transform of the time series array Air:

proc tsmodel data=mycas.air outarray=mycas.trans_array;
   id date interval=month;
   var air;
   outarrays t1;
   require tsa;
   submit;
   declare object TSA(tsa);
   rc=TSA.TRANSFORM(air, 'LOG', 0, 0, t1);
   endsubmit;
run;
