proc npar1way wilcoxon rank sum test keeps running and never completes

[r1231]

When trying do a wilcoxon rank sum test on a small comma-delimited input text file (96 obs) in PROC NPAR1WAY, the program keeps running (like stuck in an endless loop) and never completes.

How do you transform your text file into an input dataset for npar1way?

not sure what you mean. I just read the comma-delimited text file with an infile statement. That's not a problem.

Without your code or log we can barely guess. 

It could be as simple as not including a RUN or semicolon.

Please post the code you've used. 

If it is a small dataset, the frequencies of the groups you're looking at may be required as well. If you're doing an exact calculation it may take a while, though SAS usually warns you about that.

Thanks! I removed the exact statement and the code ran fine.

If you have an EXACT statement, add option MC

EXACT WILCOXON / MC N=100000;
