Similarly, databases such as the Active Duty Military Enlisted Cohort File, the Active Duty Military Personnel Transaction File, and the MEPCOM Examination and Accession File, are often used for research, studies, and analyses.
The issue of the validity of these administrative databases has been addressed in research publications by users of these databases. An example is a recent publication by Hoge et al. (2005) in which the authors found a very high correlation in their results among different administrative data systems. Also cited were publications by Miller et al. (2000) and Bell et al. (2003).
