Input all recurring independent variables

DavidLie — Tue, 19 Jan 2016 11:17:14 GMT

Hi SAS Community,

I have currently 300 variables (labelled as 'Distance1' to 'Distance300') and wish to incorporate this into proc statement. I am using Proc Mixed currently. How do I make a statement/ loop such that it automatically incorporates all the 300 variables without having to specify them manually (one by one)?

Does anyone has an idea? Comments and feedback will be greatly appreciated.

Best,

David

Usually SAS allows the construct Distance1-Distance300 to be used where a list of variables is needed.

As an alternative to @Kurt_Bremser suggestion, you could normalise the dataset, that is make a long, rather than wide dataset.

... DISTANCE_NUM DISTANCE_RES

... 1 abc

... 2 def

And then use a by statement on your procedure, i.e.

proc means data=have;
  by ... distance_num;
  var distance_res;
  output...;
run;
