[R-meta] GLMM issue with metaprop / meta package

[Dr. Guido Schwarzer]

Dear Dirk,

Recently, somebody asked the same question on GitHub (https://github.com/guido-s/meta/issues/57).

I changed the development version of meta such that the results of the common effect model are used as a fallback in metaprop() if the GLMM estimation fails (I am not sure any more whether this is a sensible approach. Any comments from the list are welcome on this.).

As Michael hinted, you can use verbose = TRUE to get more information on the estimation process. However, this is an argument of rma.glmm() from R package metafor called internally in metaprop() from R package meta.

The metaprop() call must look like the following:

metaprop(..., control = list(verbose = TRUE))

Best,
Guido
