FrantiÅ¡ek BartoÅ¡, František Bartoš, Ulrich Schimmack
Publication bias undermines meta-analytic inference, yet visual diagnostics for detecting and understanding model misfit due to publication bias are lacking. We propose the z-plot,…
Handling Missingness, Failures, and Non-Convergence in Simulation Studies: A Review of Current Practices and Recommendations
Samuel Pawel, František Bartoš, Björn S. Siepe +1
Simulation studies are commonly used in methodological research for the empirical evaluation of data analysis methods. They generate artificial data sets under specified mechanisms…
