wald.cc gives a two-sided Wald confidence interval with
continuity correction for the difference of two dependent proportions.
The continuity correction factor is *\frac{1}{n}*. Data are assumed to
be of a fourfold table, which contains the numbers of concordance
and the numbers of discordance of two dependent methods.

1 |

`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 |

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

`conf.int ` |
a confidence interval for the difference in proportions |

`estimate ` |
estimated difference in proportions |
