WebbPrior to SAS 9.1.3, PROC FREQ procedure only provided the Wald asymptotic and exact (Clopper-Pearson) confidence intervals for the binomial proportion. In SAS 9.3, when one specify the BINOMIAL (ALL) option in the TABLES statement, then all of five confidence intervals mentioned in this paper will be provided by SAS. http://www.ethps.m.u-tokyo.ac.jp/sas/index.cgi?section=34
