 +For raw and Fisher's r-to-z transformed correlation coefficients, ''[[https://wviechtb.github.io/metafor/reference/rcalc.html|rcalc()]]'' can construct the entire var-cov matrix of (partially) overlapping correlations. The var-cov matrix of dependent estimates more generally can also be constructed with the ''[[https://wviechtb.github.io/metafor/reference/vcalc.html|vcalc()]]'' function.
