We are running a meta-analysis using brms, with effect size (hedges’ g) as an outcome (mean and se). However, for some studies we were not able to reconstruct the uncertainty of the effect (se).
Is it possible to specify that the se is missing? something like
y = c(0.1, 0.2, 0.3)
y_se = c(0.1, 0.05, NA)
f = data.frame(y,y_se)
which gives me: “Stan does not support NA (in noise) in data”
