Subject: metafor::vcalc() for multiple sources of dependence
Hello Wolfgang,
Thank you for adding such an important function! In my studies, I have
quite a few studies that are structured as shown below.
Can I use vcalc() to construct a V matrix for the three sources of
dependence (i.e., multiple groups, times, outcomes) in say the study
below?
Thank you for your guidance,
Simon
