1 What Is Reproducible Research? 1 For research that relies on experiments, this can mean a researcher not involved in the original research being able to rerun the experiment, including sampling, and validate that the new results are comparable to the original ones. In computational and quantitative empirical sciences, results are replicable if independent researchers can recreate findings by following the procedures originally used to gather the data and run the computer code. Of course, it is sometimes difficult to replicate the original data set because of issues such as limited resources to gather new data or because the original study already sampled the full universe of cases.
2012]. It has even been called the “demarcation between science and non-science” [Braude, 1979, 2]. Why is replication so important for scientific inquiry? Standard to judge scientific claims Replication opens claims to scrutiny, allowing us to keep what works and discard what doesn’t. Science, according to the American Physical Society, “is the systematic enterprise of gathering knowledge . . organizing and condensing that knowledge into testable laws and theories”. The “ultimate standard” for evaluating scientific claims is whether or not the claims can be replicated [Peng, 2011, Kelly, 2006].
For example, you may want to include key parts of the code you used for your main statistical models and an explanation of this code in an appendix following your article. This is commonly referred to as literate programming [Knuth, 1992]. 4 Explicitly tie your files together If everything is just a text file, then research projects can be thought of as individual text files that have a relationship with one another. They are tied together. A data file is used as input for an analysis file. The results of an analysis are shown and discussed in a markup file that is used to create a PDF document.
