A Comparison of Rasch Person Analysis and Robust Estimators.
Smith, Richard M.
Educational and Psychological Measurement, v45 n3 p433-44 Aut 1985
Standard maximum likeliheed estimation was compared using two forms of robust estimation, BIWEIGHT (based on Tukey's Biweight) and AMTJACK (AMT-Robustified Jackknife), and Rasch model person analysis. The two procedures recovered the generating parameters, but Rasch person analysis also helped to identify the nature of a response disturbance. (GDC)
