  • Title: Exact one-sided confidence limits for the difference between two correlated proportions.
    Author: Lloyd CJ, Moldovan MV.
    Journal: Stat Med; 2007 Aug 15; 26(18):3369-84. PubMed ID: 17315269.
    Abstract:
    We construct exact and optimal one-sided upper and lower confidence bounds for the difference between two probabilities based on matched binary pairs using well-established optimality theory of Buehler. Starting with five different approximate lower and upper limits, we adjust them to have coverage probability exactly equal to the desired nominal level and then compare the resulting exact limits by their mean size. Exact limits based on the signed root likelihood ratio statistic are preferred and recommended for practical use.
