Thanks to [Daniel Quintana][1] and his [blogpost][2] about statistical power calculation for meta-analysis I wrote an excel calculator for my daily work and started to work further on that topic...
In the project Database you'll find the 2.0 version of my excel calculator, now with fixed and random effects models and several R-scripts, I advanced from Daniel's.
