A Strategy for the Graphical Representation of Rasch Model Residuals.
Ludlow, Larry H.
Educational and Psychological Measurement, v45 n4 p851-59 Win 1985
When the parameters of item response data are estimated by a latent trait model, some variation will remain unaccounted. If baseline graphical configurations of the residual variation can be constructed, measurement irregularities may be exposed. An analytic strategy for the graphical representation and analysis of Rasch model residuals is presented. (Author/LMO)
