A note on Wilson coverage intervals for proportions estimated from complex samples

Abstract

This note discusses the theoretical foundations for the extension of the Wilson two-sided coverage interval to an estimated proportion computed from complex survey data. The interval is shown to be asymptotically equivalent to an interval derived from a logistic transformation. A mildly better version is discussed, but users may prefer constructing a one-sided interval already in the literature.

Key Words:      Effective sample size; Confidence interval; Logistic transformation.
