Hello all,
I am running a metanalysis using a precomputed effect size and standard error.
I have no issues declaring the data for the metanalysis but when I select the random effect models for these analysis I get the error "Convergence not achieved during tau2 estimation". Summary command runs when I use a fixed-effect model but this type of model is not appropriate for the analysis of the data.
**************code*************
meta set Meanatbaseline SDbaseline if ( _Study_design=="A" ), studylabel(_author_year) studysize( _pop) eslabel( baseline )
(75 missing values generated)
Meta-analysis setting information
Study information
No. of studies: 15
Study label: _author_year
Study size: _pop
Effect size
Type: Generic
Label: baseline
Variable: Meanatbaseline
Precision
Std. Err.: SDbaseline
CI: [_meta_cil, _meta_ciu]
CI level: 95%
Model and method
Model: Random-effects
Method: REML
. meta summarize
Convergence not achieved during tau2 estimation
thank you for your help
