The One Parameter Logistic Modelibility of the two-parameter logistic model. In the OPLM, difficulty parameters are estimated and discrimination indices imputed as known constants. Imposing a very mild restriction on these indices makes it possible to apply CML to this model. Moreover, the model is an exponential family which make

Mixture Distribution Rasch Modelsolds within subpopulations of individuals, but with different parameter values in each subgroup. These subpopulations are not defined by manifest indicators, rather they have to be identified by applying the model. Model equations are derived by conditioning out the class-specific ability parameters

Polytomous Rasch Models and their Estimationical Statistics and Probability. The various versions of the basic model, suggested in the literature, are briefly mentioned and compared. The main part of the chapter deals with estimation problems, theoretically as well as numerically. The connection to the RC-association models is discussed, and
