Biweight Estimates of Latent Ability.
MisLevy, Robert J.; Bock, R. Darrell
Educational and Psychological Measurement, v42 n3 p725-37 Fall 1982
An alternative biweight estimator based on Tukey's is examined in which (1) test disturbances are not assumed to be the same for all subjects, (2) each response is utilized proportional to its value, and (3) the biweight and maximum likelihood estimate agree when no disturbances are present. Smaller mean-squared errors are shown. (Author/CM)
