## 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 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

### Examples

    diffpropci.mp(b = 40, c = 20, n = 160, conf.level = 0.95)
