If you’ve ever run a regression with more than a handful of variables, you know the problem. It’s called model uncertainty: which variables should go into the baseline? One solution is to simply put all in one model, but doing so attenuates precision. Another approach is to get rid of the variables that are more difficult to interpret, but that’s not kosher either: It is important to realize that this uncertainty is an inherent part of economic modelling, whether we acknowled

Towards a Credibility Revolution: Why successful replication remains unlikely

by T.D. Stanley and Chris Doucouliagos Power Failure Recent meta-science studies find that psychology is typically 4 times more powerful than medical research (9%), and its median power is twice as large as economics (18%).[1, 2, 3] Yet, only 8% of psychological studies are adequately powered. Statistical power is the probability that a study of a given precision (or sample size) will find a statistical significant effect. Following Cohen, adequate power (80%) has been deemed

Past Discussions on Common Pitfalls in Conducting Meta-Regression Analysis in Economics

Topics covered previously using t-values as effect sizes reducing economic effects or tests to categories of statistical significance for the purpose of probit (or logit) meta-regression analysis (MRA). There is a consensus among MAER-Net members that these are ‘pitfalls’ in the sense they are often misinterpreted and/or poorly modelled.  MAER-Net does not wish to ‘prohibit’ the use of logit/probit or t-values in meta-analysis.  We merely caution those who choose to do so to
