st: Diagnostic test characteristic estimation without gold standard

[Doherr Marcus <marcus.doherr@itn.unibe.ch>]

In the evaluation of diagnostic test characteristics, one is often faced
with the problem of several tests but no "true" gold standard.

There is an algorithm using Gibbs sampling to estimate the sensitivity and
specificity of two (or more) diagnostic tests in the absence of a gold
standard. Has this approach already been integrated into a STATA routine
(module) yet? If yes, is this freely available?

Thanks a lot - Regards
