| Tiivistelmä: | To evaluate the performance of estimators designed to handle sample selection bias, the authors analyse data from a Norwegian rehabilation project with a randomised experimential design. The data permit them to compare the performance of different nonexperimental estimators with the experimental results. In the case study the authors find that nonexperimental evaluation based on sample selection estimators with selection terms that fail to meet conventional levels of statistical significance is highly unreliable. |
