What is push button replication?
PBR research attempts to confirm the validity of published results using both the original data and the programming code from a study. The premise behind a PBR study is that the third party researcher should not need to make any significant adjustments, write new code or conduct additional analysis in order to arrive at the published results. Thus, a PBR is a step that precedes pure replication.
While a pure replication asks the question can we reproduce the published results using the original data and the methods described in the original study, a PBR tries to verify if we can use the original authors’ programming code with the original data to reproduce the published results. Through pure replication studies, researchers can potentially uncover errors where the programming code incorrectly implements the estimation methods described by the researchers of the original study. PBR studies, on the other hand, can help reveal instances where there are no or insufficient data and code available or where the programmes do not run.
