[R-meta] integrating SMD, ZCOR and ZPCOR
Dear Katrin If I were using different effect size types I would regard it as almost obligatory to include a categorical moderator to differentiate them. However in this case they are so different that I would begin to doubt the desirability of doing one overall analysis. Michael

Dear all, With the "escalc" function I calculated different effect sizes depending on the existing data (SMD, ZCOR, ZPCOR). For obtaining overall effects, can I treat the resulting yi in the same way? I mean, can I just integrate them in my random effect model by the "rma.uni" function without specifying what kind of effect size it is? And how to interpret resulting overall effect sizes? Can these be interpreted like Cohen's d? Kind regards, Katrin
