An Analysis of the Comparison Groups in the CLMS (Continuous Longitudinal Manpower Survey) Public Use Tapes

摘要

The study systematically evaluated the comparison groups in the Continuous Longitudinal Manpower Survey (CLMS) public use tapes. The purpose of the evaluation was to identify the comparison group(s) most appropriate for net impact estimation. This was done by a series of Chow tests that identified whether or not participation in the program was random between participants in the program and non-participants (the comparison groups).
