I am working on the last part of my meta-analysis. I am using a random-effects model. I am looking at uncontrolled effect sizes (difference between pre-test and post-test scores using Cohen's d).
I need to conduct a test for publication bias.
1) Given the type of meta-analysis I am running, what test should I use? I feel like based on what I read, this may be the Deeks' test.
2) I seem unable to find the formula for the any form of the tests. Could someone provide a reference that has (hopefully, easy to understand) the formula needed?
