All,

I am doing a meta-analysis where our response variable is CV of effect
sizes (e.g., CV = sd/mean, where sd and mean are calculated from multiple
effect sizes from the same study).

Does anyone know the appropriate way to weight CV?  We want to weight CV to
account for different sampling effort and uncertainty in the CV among
studies.  We can use standard deviation/variance of CV, but that
calculation includes CV in it(!!), so that larger CVs have smaller
variances, and vice versa (at least in our dataset).  What about weighting
CV by 1/sample size instead?

Thanks for any guidance!
