st: Credible interval of median odds ratio (MOR)

[Dirk Enzmann <dirk.enzmann@uni-hamburg.de>]

The following referenced article by Merlo et al. (2006) shows (eq. 6, p. 
294) how to calculate the median odds ratio (MOR) as a measure of 
heterogeneity in logistic multilevel regression models (as an 
alternative to the ICC) (how to calculate this is shown even better in 
Rabe-Hesketh & Skrondal, 2008, p. 257).

Merlo et al. go on and calculate the "95% credible interval" around the 
MOR (p. 294). Lars Kroll's ado -xtmrho- (SSC) calculates the MOR in Stata.

Does anybody know whether there is already a solution to calculate "95% 
credible interval" of the MOR in Stata, too? Or, how to do using 
ereturns of a multilevel logistic regression model (either using 
-xtmelogit- or -gllamm-)?
