ranktest {metafor} | R Documentation |
The function ranktest
is generic. It can be used to carry out the rank correlation test for funnel plot asymmetry as described by Begg and Mazumdar (1994).
ranktest(x, ...)
x |
an object of class "rma" . |
... |
other arguments. |
Currently, there is only a method for handling objects of class "rma"
with the ranktest
function. Accordingly, the corresponding method is called ranktest.rma
. See the documentation for that function for more details.
