WebbPROC FREQ provides Wald and exact (Clopper-Pearson) confidence limits for the binomial proportion. You can also request the following binomial confidence limit types by specifying the BINOMIAL(CL=) option: Agresti-Coull, Blaker, Jeffreys, exact mid-p, likelihood ratio, logit, and Wilson (score).For more information, see Brown, Cai, and DasGupta (), … WebbSample size for Wilsons confidence interval.
