Hello all.
I am trying to calculated pooled estimates of disease prevalence using METAN command.
In trying to generate the funnel plot (METAFUNNEL command) the below error comes
standard error of theta must exceed 0 in each study
Is there a way to deal with the zero value - I suspect in the column called _seES? Is it just the zero values in the seES to worry about or also in the column for _ES?
I thought adding a tiny arbitrary value e.g. 0.0000001 to replace the 0 in the _seES and _ES could work but it seem 'dodgy' to me
Any thoughts?
Thanks
