Using Longitudinal Data to Estimate Reliability in the Presence of Correlated Measurement Errors.
Werts, C. E.; And Others
Educational and Psychological Measurement, v40 n1 p19-29 Spr 1980
Test-retest correlations can lead to biased reliability estimates when there is instability of true scores and/or when measurement errors are correlated. Using three administrations of the Test of Standard Written English and essay ratings, an analysis is demonstrated which separates true score instability and correlated errors. (Author/BW)
