[R-meta] Binomial Effect Size Display?

[Mark White]

Hello all,

Many meta-analyses will take their smaller-than-they-would-have-hoped
summary effect size and make it look bigger by using Rosenthal and Rubin's
(1982) binomial effect size display:
http://www.cognadev.com/publications/BESD_Rosenthal_and_Rubin_1982.pdf. I
have always thought this is a misleading metric. Someone asked a question 5
years ago on CrossValidated about it, and I tried to answer it with a
little simulation:
https://stats.stackexchange.com/questions/24067/is-the-binomial-effect-size-display-besd-a-misleading-representation-of-effect
(this post provides a good, short summary of the original paper and the
metric, if you are unfamiliar with it).

I'm more of a simulate-and-see-if-it-works type of person—is there anyone
who understands more of the math behind *why* this metric might be
misleading?

Best,
Mark
