Subject   st: Sample size for estimating negative predictive value and sensitivity
Date   Mon, 5 Sep 2011 01:27:09 +0800

I am working on a research to compare the diagnostic accuracy of two
qualitative (binary) diagnostic methods. How do you compute for the
minimum required sample size for determining the sensitivity and
negative predictive values of these two diagnostic methods using
Stata?

Thank you.
