Accuracy of Asymptotic Standard Errors of the Maximum and Weighted Likelihood Estimators of Proficiency Levels With Short Tests KU Leuven
The maximum likelihood (ML) and the weighted likelihood (WL) estimators are commonly used to obtain proficiency level estimates with pre-calibrated item parameters. Both estimators have the same asymptotic standard error (ASE) that can be easily derived from the expected information function of the test. However, the accuracy of this asymptotic formula is unclear with short tests when only a few items are administered. The purpose of this paper ...
