In PropCIs: Various Confidence Interval Methods for Proportions

Description

Adjusted Wald interval for a difference of proportions with matched pairs. This is the interval called Wald+2 in Agresti and Min (2005). Adds 0.5 to each cell before constructing the Wald CI

Usage

diffpropci.mp(b, c, n, conf.level)

Arguments

b	off-diag count
c	off-diag count
n	sample size
conf.level	confidence coefficient 1-α

Details

The interval is truncated, when it overshoots the boundary

Value

A list with class '"htest"' containing the following components:

conf.int	a confidence interval for the difference in proportions.
estimate	estimated difference in proportions
