Estimating True Scores and True Group Means from Multiple Independent Measures.
Werts, Charles E.; Linn, Robert L.
Given multiple independent measures of an underlying true factor and information on group membership, it is possible to compute a set of observed group means for each measure. Given at least three tests, these sets of means may be used to compute the reliability of the means for each test. The procedure for estimating true scores from the reliabilities of the individual tests and the group means is derived. (For related document, see TM 002 301.) (Author)
