[R-meta] nesting an inner | outer formula

[Ross Neville]

Hi Wolfgang

I hope this email finds you well

I was wondering if you could tell me whether the following list of random
effects can be updated to make the the inner | outer formula conditional.

random = list (~ 1 | StudyID, ~ Informant | TreatmentGroup)

I would like for the different levels of Informant to be correlated within
TreatmentGroup within StudyID, and I would like the different levels of
TreatmentGroup to be correlated within StudyID too.

In SAS Proc Mixed, I've managed to run this model and I want to replicate
it in metafor rma.mv.

random StudyID;
random Informant/subject=StudyID, group=TreatmentGroup type=un;
parms  1  1 1 1  1 1 1  1 1 1  1 1 1  1/hold=14;

Any help you can provide to let me know if this is possible in rma.mv would
be much appreciated.

Regards
Ross
