[R-meta] F test vs QM test for test of moderators

[Huang Wu]

Dear all,

I am writing to ask about the Test of Moderators in meta-analysis.
Specifically, I am curious about the appropriate test to use between the F
test and QM test. I ran the following code and obtained results using the F
test for the Test of Moderators. However, I would like to explore how to
obtain QM test results.

Could you kindly advise me on the suitable test to use and how to obtain QM
test results using the metafor package?

Thank you for your assistance.
Huang
