(2005). Simple improved confidence intervals for comparing matched proportions. Statistics in Medicine 24, 729-740. --- a portion of a Google cached U.Fla web site, probably by AgrestiR code for the adjustment of the Wald confidence interval for a difference of proportions, with matched pairs. This is the interval called Wald+2 in Agresti and Min, Statistics in Medicine, 2004, which adds 0.5 to each cell before constructing the Wald CI. The CI is truncated when it overshoots the boundary. 1) ul = 1
