## Calculates a Wilson confidence interval

### Description

wilson gives a two-sided Wilson confidence interval for the difference of two dependent proportions. There is no continuity correction performed. Data are assumed to be of a fourfold table, which contains the numbers of concordance and the numbers of discordance of two dependent methods.

### Usage

wilson(a, b, c, d, n, alpha)


### Arguments

 a first number of concordant paires as described above b first number of discordant paires as described above c second number of discordant paires as described above d second number of concordant paires as described above n number of observed objects alpha type I error; between zero and one

### 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
