Student Projects

A number of student papers are posted here, accompanied by complete replication documentation modeled on the TIER Protocol. Try downloading one of these papers to see if you can successfully replicate the study.

We would like to hear about what works well and where you run into difficulty, so please send us a message (info@projecttier.org) to tell us about your experience trying to replicate these studies.

Information about the documentation posted here:

• Why are the contents and organization of the replication documentation not the same for all the studies posted here?

  All the students who wrote these projects were guided by the TIER Protocol when they created their replication documentation. However, because the Protocol has been through various versions, and because different instructors customize the instructions they give their students to suit their particular circumstances, the contents and organization of the replication documentation vary across these papers. But in all cases, a Read Me file explains what is contained in the documentation and how it can be used to replicate the study.

• Should I use the documentation posted on Dataverse, or the zipped folders available for download here?

  You may find that the results of the papers can be reproduced more reliably if you use the documentation in the zipped folders available for download here, as opposed to the documentation available on Dataverse. This has to do with some technical features of Dataverse. (For example, Dataverse converts data files that are saved in the formats of proprietary software (e.g., .xlsx, .dta and .sav) to a generic tab delimited format (.tab), so code in command files that calls data files using proprietary extensions might fail to run; and the directory structure in which files are stored is not preserved when they are uploaded to Dataverse, so code that uses relative directory paths might fail to run.)
