Description: Provides meta-analysis methods that correct for
publication bias. Four methods are currently included in the package.
The p-uniform method as described in van Assen, van Aert, and Wicherts (2015)
<doi:10.1037/met0000025> can be used for estimating the average effect size,
testing the null hypothesis of no effect, and testing for publication bias
using only the statistically significant effect sizes of primary studies. The
second method in the package is the p-uniform* method as described in Chapter
5 of van Aert (2018) <doi:10.31222/osf.io/eqhjd>. This method is an extension
of the p-uniform method that allows for estimation of the average effect size
and the between-study variance in a meta-analysis, and uses both the statistically
significant and nonsignificant effect sizes. The third method in the package
is the hybrid method as described in van Aert and van Assen (2017)
<doi:10.3758/s13428-017-0967-6>. The hybrid method is a meta-analysis method
for combining an original study and replication and while taking into account
statistical significance of the  original study. The p-uniform and hybrid method
are based on the statistical theory that the distribution of p-values is
uniform conditional on the population effect size. The fourth method in the
package is the Snapshot Bayesian Hybrid Meta-Analysis Method as described in
van Aert and van Assen (2017) <doi:10.1371/journal.pone.0175302>. This method
computes posterior probabilities for four true effect sizes (no, small, medium,
and large) based on an original study and replication while taking into account
publication bias in the original study. The method can also be used for computing
the required sample size of the replication akin to power analysis in null
hypothesis significance testing.
