Derivations of the Rasch Modelhe unweighted raw score, existence of conditional maximum likelihood estimators of the model parameters and of conditional likelihood ratio tests for hypothesis testing - suggest the question as to whether they are shared by a larger class of IRT models, or whether they are, within a certain framewo

On Person Parameter Estimation in the Dichotomous Rasch Model estimators: the maximum likelihood, the Bayes modal, the weighted maximum likelihood, and the Bayes expected a posteriori estimator. In Section 4.4 a simulation study is presented in which properties of the estimators are evaluated. Section 4.5 covers randomized confidence intervals for person para

Testing the Rasch Modelhown how tests for this framework can be adapted to the Rasch model. Four types of tests are considered: generalized Pearson tests, likelihood ratio tests, Wald tests, and likelihood ratio tests. The statistics presented not only support the purpose of a global overall model test, but also provide i

Linear Logistic Models for Changeals with this reinterpretation. Moreover, the LLTM for change can be reparameterized in such a way that - quite unlike the RM - change in multidimensional item domains can be analyzed and monitored- This model is called the ‘linear logistic model with relaxed Assumption’ (LLRA) because it dispenses
