Hello,
I'm new to the forum - I'm doing meta-regression analyses with metareg on a relatively small number of studies (about 50)
I have tried several predictors, without problems, but for just this one (onAD, which is significant) I'm reading an output without the value of R squared.
This is puzzling since in several cases (nonsignificant predictors) I even get negative R squared.
anyone has an idea?
thanks a lot in advance for your help,
Martino Belvederi
. metareg ESraw onAD if metareg2==1, wsse(ES_SE) bsest(reml)
Meta-regression Number of obs = 43
REML estimate of between-study variance tau2 = 0
% residual variation due to heterogeneity I-squared_res = 28.26%
Proportion of between-study variance explained Adj R-squared = .%
