Dear R-help, I'm using prop.test() to compute a confidence interval for a proportion under R version 2.4.1, as in:
prop.test(x = 340, n = 400)$conf [1] 0.8103309 0.8827749 I have two questions: 1) from the source code my understanding is that the confidence interval is computed according to Wilson, E.B. (1927) Probable inference, the law of succession, and statistical inference. J. Am. Stat. Assoc., 22:209-212. Is it correct? 2) The doc says "Continuity correction is used only if it does not exceed the difference between sample and null proportions in absolute value." Does someone has a reference in which this point is discussed? Best, -- Jean R. Lobry ([EMAIL PROTECTED]) Laboratoire BBE-CNRS-UMR-5558, Univ. C.
