In recent years, the replicability of original findings published in psychology journals has been questioned. We show that the replicability of a randomly chosen result cannot exceed population mean power, so that estimates of mean power are optimistic estimates of replicability. We then present two methods that can be used to estimate mean power for a heterogeneous set of studies with significant results: Maximum Likelihood and Zcurve. We present the results of two large-scale simulation… Expand
