The role and value of replication in empirical software engineering results

We show that there is substantial evidence to suggest that current approaches to empirical replications are highly problematic. There is a consensus that replications are important, but there is a need for better reporting of both original and replicated studies. Given the low power and incomplete reporting of many original studies, it can be unclear the extent to which a replication is confirmatory and to what extent it yields additional knowledge to the software engineering community. We recommend attention is switched from replication research to meta-analysis.
