Hello,

I'm currently on a set of data and conducting a meta-analysis with metan. For the results I do need the prediction intervals but I always get the following error:

Error in predictive interval data
Error in metan.BuildResultsSet
(Note: meta-analysis model was fitted successfully)
r(9);
This is the simplified code I use:

gen logRR=log(RR)
gen loglc=log(lc)
gen loguc=log(uc)
metan logRR loglc loguc if analysis==1, lcols(author year cases_total) random eform rfdist
I seriously do not know what's the problem, really would appreciate it if someone could give me a hint.
Thanks in advance and all the best,

Alex
