I'm trying the packages meta and metagen to perform a meta-analysis study.
With meta I write this and it provides both results, for fixed effects and mixed effects.
With metafor I must use two different calls:
rma(myX,sei=mySD, method="ML", measure="OR") # Random effects.
rma(myX,sei=mySD, method="FE", measure="OR") # Fixed effects.
But strangely the "random-effects" option on metafor produces the same result than the fixed-effects option of meta and vice versa. I mean they are reversed.
What am I doing wrong?
