[R-meta] double arcsine transformation
Dear James I know this is not what you asked but are you sure you want to do univariate analyses here? Although sensitivity and specificity are independent within study in general they are not independent between study. It may be that you have too few studies to do the bivariate analysis of course.

I am performing a univariate meta-analysis on sensitivity and specificity. I fit the model in metafor and when trying to transform the double-arcsine I get the following error: pes<-predict(pes.dat,transf.ipft.hm,targ=list(ni=dat$total)) Error in predict.rma(pes.dat, transf.ipft.hm, targ = list(ni = dat$total)) : Cannot specify new moderator values for models without moderators. Is this fixable or do you need more information. James C Meyer DVM DACVIM
