Hello Meta-Analysis Experts, I'm exploring some apparently undocumented, extractable objects from fitted metafor::rma.mv() models. Specifically, I was wondering what do the following undocumented boolean objects denote (withS, withG, withH, and withR)? Much appreciated, Jack library(metafor) dat <- dat.konstantopoulos2011 m1 <- rma.mv(yi, vi, random = ~ 1 | district/study, data = dat)
m1$withS m1$withG m1$withH m1$withR
Hi Jack, withS indicates whether there are any '~ 1 | id' random effects. withG and withH are for the presence of a first and second "~ var1 | var2' random effect. withR indicates whether a known correlation matrix has been specified for some '~ 1 | id' random effect. Ultimately, you can always look at the source code directly: https://github.com/wviechtb/metafor/blob/master/R/rma.mv.r Best, Wolfgang

Very informative, thanks very much Wolfgang! Kind regards, Jack On Wed, Aug 18, 2021 at 7:13 AM Viechtbauer, Wolfgang (SP) <
