I recently gave a lab presentation on the work we have been doing to attempt to mitigate the nefarious effects of publication bias, and I thought I’d share the slides here. The first iteration of the method (details given in Guan and Vandekerckhove, 2016), summarized in the first half of the slides, could be applied to single studies or to cases where a fixed effects meta-analysis would be appropriate. I have been working to extend the method to cases where one would perform a random-effects meta-analysis to account for heterogeneity in effects across studies, summarized in the second half of the slides. We’re working now to write this extension up and tidy up the code for dissemination.
Here are the slides (pdf):
