For the computing of confidence intervals for difference between two independent binomial proportions in SAS 9.4/STAT 12.3, it’s hard to figure out exactly how many methods are available because there is no “CL=ALL” trigger in RISKDIFF option (but you can get one in BIONOMIAL option to compute the confidence intervals for binomial proportion). As far […]

Confidence Intervals for Binomial Proportion: A SAS 9.4/STAT 12.3 Update
After getting the access to SAS 9.4 alone with SAS/STAT 12.3, I first took a look at my favorite SAS statistical procedure, PROF FREQ. Last year I had a note on confidence intervals for binomial proportion based on SAS 9.2/SAS9.3. Now it’s time to throw out some updates. 1. A new confidence limits method added, […]
Statistical Notes (5): Confidence Intervals for Difference Between Independent Binomial Proportions Using SAS
A guy notices a bunch of targets scattered over a barn wall, and in the center of each, in the "bulls-eye," is a bullet hole. "Wow," he says to the farmer, "that’s pretty good shooting. How’d you do it?" "Oh," says the farmer, "it was easy. I painted the targets after I shot the holes." […]
