Abstract

<abstract abstract-type="main" id="sim5561-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p id="sim5561-para-0001">For matched‐pair binary data, a variety of approaches have been proposed for the construction of a confidence interval (CI) for the difference of marginal probabilities between two procedures. The score‐based approximate CI has been shown to outperform other asymptotic CIs. Tango's method provides a score CI by inverting a score test statistic using an iterative procedure. In this paper, we propose an efficient non‐iterative method with closed‐form expression to calculate Tango's CIs. Examples illustrate the practical application of the new approach.
