exact.midp {diffdepprop} | R Documentation |
exact.midp gives a two-sided exact conditional confidence interval for the difference of two dependent proportions. It is built of a mid-p Interval. Data are assumed to be of a fourfold table, which contains the numbers of concordance and the numbers of discordance of two dependent methods.
exact.midp(b, c, n, alpha)
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:
