Measuring Change across Multiple Occasions Using the Rasch Rating Scale Model.
Wolfe, Edward W.; Chiu, Chris W. T.
Journal of Outcome Measurement, v3 n4 p360-81 1999
Describes a Rasch rating scale analysis of a multi-occasion evaluation that produces confusing results when subjected to separate calibrations. Applies a correction algorithm developed by B. Wright (1996) to show how the Wright algorithm can reduce misfit to the Rasch rating scale model as well as changing the interpretation of change. (SLD)
