Good day: Here is my data (x_data):
Treat outcome count
A x 10
A y 0
B x 0
B y 20
proc freq data=x_data;
title "Agresti-Min (Exact);
tables treat*outcome /riskdiff(cl=(exact));
weight count;
exact riskdiff(method=score2);
run;
The output (attached) gives an Exact 95% Confidence Limit on the difference as 0.7000 to 0.0000. Other methods within proc freq don't do this (they all give 1.000 as an upper limit). I recognize some methods may fall apart when count=0...but, by definition, the lower limit can't be greater than the upper limit. Is this a known error or what?
I raised this issue with SAS and they responded as follows:
"R&D have had a closer look at the issue and agree this is a new bug and will be raising a Defect and SAS Usage Note.
The issue will be fixed in a future release of SAS."
As you were 😉
