diffpropci.mp: Adjusted Wald interval for a difference of proportions with matched pairs

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

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

Details

The interval is truncated, when it overshoots the boundary
