Abstract: rdiff is an immediate command that constructs a 95% confidence interval for the difference between two independent binomial proportions. Besides the most well-known method —— normal approximation method —— which may produce undesirable results in extreme cases, the more remarkable method, Wilson score method, is also available. Note that rdiff is recommended only for the case where the proportion of #succ1 for #n1 is equal to or greater than the proportion of #succ2 for #n2.
