[R-meta] Separate tau for each subgroup in mixed-effect models

Hi all,

I plan to fit a mixed-effects meta-regression model with metafor::rma(). The moderator would be categorical (3 subgroups). If I’m not mistaken, rma() estimates a common tau^2 across subgroups.

Is it possible to estimate a separate tau for each subgroup?

I believe it is possible in the {meta} package through the tau.common argument (https://cran.r-project.org/web/packages/meta/meta.pdf).
