[R-meta] question on multilevel model results
Dear Michael, Yes, Thank you!! It is indeed very useful for I^2 in multilevel models. But I was also wondering how to obtain Tau and Tau-squared in multilevel models? And if such a thing is possible? Kind regards, Gabriel On Thu, Jul 27, 2023 at 1:22?PM Michael Dewey <lists at dewey.myzen.co.uk> wrote:

Hello all, I would like to ask why, conversely, rma() objects for rma.mv() objects (with and without moderators ) in the summary report do not provide
values
of heterogeneity measures besides Cohen's *Q* such as "tau/hat/ square"
or
"tau/square" or H^2?
Is this maybe because this type of model (rma.mv()) does not allow the
estimation of these measures?
Alternately, could they be calculated separately for rma.mv() objects?
If so, is there a code for doing this ?
Thanks a lot.
Kind regards,
Gabriel
