Sensitivity of the Linear Logistic Test Model to Misspecification of the Weight Matrix.

Baker, Frank B.

Applied Psychological Measurement, v17 n3 p201-10 Sep 1993

Using simulation, the effect that misspecification of elements in the weight matrix has on estimates of basic parameters of the linear logistic test model was studied. Results indicate that, because specifying elements of the weight matrix is a subjective process, it must be done with great care. (SLD)
