Abstract:
Reproducibility is obtaining the same results when re-analyzing the same data. It can be used to confirm the findings reported in a focal study and serve as a preliminary step in the replication process. This presentation will discuss why reproducibility has become an important part of the research process, describe how to test it, report on findings from applying those tests to published work, relate their relevance to replication, and offer recommendations for the publication process.
