An Investigation of the Sampling Distributions of Equating Coefficients.
Peer reviewed Peer reviewed
Baker, Frank B. – Applied Psychological Measurement, 1996
Using the characteristic curve method for dichotomously scored test items, the sampling distributions of equating coefficients were examined. Simulations indicate that for the equating conditions studied, the sampling distributions of the equating coefficients appear to have acceptable characteristics, suggesting confidence in the values obtained…

Standard Errors of Levine Linear Equating.
Peer reviewed Peer reviewed
Hanson, Bradley A.; And Others – Applied Psychological Measurement, 1993
The delta method was used to derive standard errors (SES) of the Levine observed score and Levine true score linear test equating methods using data from two test forms. SES derived without the normality assumption and bootstrap SES were very close. The situation with skewed score distributions is also discussed. (SLD)
