Egger's
test? Dear Wolfgang and colleagues, A query as my collaborators and I finalize a paper that fits a
multi-level model
using the rma.mv function (with thanks to this list for advice on a post
a few
months ago): Are there recent developments in research on sensitivity tests for this
type of
nested data structure, including valid funnel plot and Egger's test
diagnostics?

we
haven't yet found any more recent information on the topic. Advice is
welcome -
and if such tests are not yet available, we'd be thankful for references

published sources that note this. With thanks, Jenny Dr. Jennifer Oser Department of Politics & Government | Ben-Gurion University of the Negev Department website | Research and teaching website
