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

wald.cc(b, c, n, alpha)


### Arguments

 b first number of discordant pairs in a fourfold table as described above c second number of discordant pairs in a fourfold table as described above n number of observed objects alpha type I error; between zero and one
