wald.cc {diffdepprop} | R Documentation |
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.
