Hi,
I am currently conducting a meta analyses and wish to carry out
Egger's test. I was just wondering, does the weighted linear
regression model proposed by Egger et al correspond to the "weighted
regression with multiplicative dispersion" option in Metafor?
Dear Sultan
One thing I would suggest is to also use the ranktest function. In my
experience they can give different results. You also need to look at
the funnel plot of course and bear in mind that none of these methods
is very satisfactory unless you have quite a number of fairly
homogenous studies to synthesise.
Many thanks
Sultan
