Dear Listers,
 
Stata 8.2
 
I did .predict eb after performing a .metandi a b c d and received the following message:
 
. predict eb
(option mu assumed; posterior predicted Se & Sp)
log-likelihood cannot be computed
for observations that should not contribute to posterior or ll,
   set response variable to missing
r(198);

I would appreciate it if someone could explain this error message to me and how I can by-pass/overcome the error.
 
Btw, this is my metandi:
 
. which metandi
