for the difference between two non-independent proportions?
For example, let:
N = no. of patients
p1 = proportion of asymptomatic (vs. symptomatic) patients
p2 = proportion of asymptomatic (vs. symptomatic) patients
How would one get the 95% CI for (p2 - p1)?
The McNemar test can be used to test whether (p2 - p1) differs
significantly from 0, but it does not supply a means of getting
a confidence interval.
The only literature I've located is a note by CC Hsieh in
Stat Med (1985):
but so far I've been unable to see the article and don't know
what method it used.
Thanks in advance.
