Equivalent Linear Logistic Test Models.

Bechger, Timo M.; Verstralen, Huub H. F. M.; Verhelst, Norma D.

Psychometrika, v67 n1 p123-36 Mar 2002

Discusses the Linear Logistic Test Model (LLTM) and demonstrates that there are many equivalent ways to specify a model. Analyzed a real data set (300 responses to 5 analogies) using a Lagrange multiplier test for the specification of the model, and demonstrated that there may be many ways to change the specification of an LLTM and achieve the same improvement in model fit.
