A Comparison of the Rasch Separate Calibration and Between-Fit Methods of Detecting Item Bias.
Smith, Richard M.
Educational and Psychological Measurement, v56 n3 p403-18 Jun 1996
The separate calibration t-test approach of B. Wright and M. Stone (1979) and the common calibration between-fit approach of B. Wright, R. Mead, and R. Draba (1976) appeared to have similar Type I error rates and similar power to detect item bias within a Rasch framework. (SLD)
