| Tiivistelmä: | This article demonstrates that the portfolio approach could suffer a serious problem when the sorting variables contain not only true values but also measurement errors. The grouped measurement errors are embedded into the data used to test financial models and further bias the testing results. To correct for this measurement-error problem, the author develops a random sampling approach to form portfolios. |
