Here's some SAS code to do a randomization test on almost any test SAS can generate in a proc. These macros form a wrapper about the desired proc. I'll be talking about this at SUGI in April. I hope you don't mind attachments; they're short.

(See attached file: Rand_gen.sas)(See attached file: rand_anl.sas)

And here's a simple example showing how to use the macros. Just take whatever proc you wanted to run the randomization test on, and insert the statement "BY REPLICATE;" in it. Then, in the rand_anl.sas macro call, specify the records to be tested in the output data set:

%include 'rand_gen.sas'; %include 'rand_anl.sas';

%rand_gen(indata=yb98fish,outdata=outrand,depvar=FishS,numreps=1000,seed=12345678);

proc glm data=outrand noprint outstat=outstat1; by replicate; class habitat; model FishS = habitat; means habitat / tukey hovtest ; run;

%rand_anl(randdata=outstat1,where=_source_='Habitat' and _type_='SS3',testprob=prob, testlabel=Model F test);

In my talk at SUGI, I'll show how to use this in more detail, explain how the macro wrapper works, and show how to use this in more sophisticated situations [including an ODS dataset].
