Some Observations on the Estimation of True Scores.
Livingston, Samuel A.
The procedure of estimating true scores by means of a transformation of the obtained score based on the reliability coefficient is compared with the use of the obtained score without transformation. Using the mean squared error as a criterion, the transformed score is a better estimate for most examinees but poorer for those whose true scores lie furthest from the mean. An example is provided.
