Fig. 3: Histogram of the percentage change of MAIVE relative to PET-PEESE.
From: Spurious precision in meta-analysis of observational research

Notes: The figure compares the results, in absolute value, of MAIVE and PET-PEESE for the sample of economics meta-analyses56. Only meta-analyses with the FÂ >Â 100 from the first-stage regression of MAIVE are included. In most cases, MAIVE adjustment moves PET-PEESE estimates closer to zero.
