A Proposed Hybrid Effect Size Plus $p$-Value Criterion: A Replication of Goodman et al. (2019)

In a recent simulation study, Goodman et al. (2019) compare several methods with regard to their performance of type I and type II error rates in case of a thick null hypothesis that includes all values that are practically equivalent to the point null hypothesis. They propose a hybrid decision criterion only declaring a result "significant" if both a small $p$-value and a sufficiently large effect size are obtained. We successfully replicate the results using our own software code in R and discuss an additional decision method that maintains a pre-defined false positive rate. We confirm that the hybrid decision criterion has comparably low error rates in settings one can check for but point out that the false discovery rate cannot be easily controlled by the researcher.
