Collateral information and Mixed Rasch models
نویسندگان
چکیده
A simulation study is conducted to evaluate the usefulness of incorporating collateral information in the Mixed Rasch model. The results show that the standard errors as well as latent class membership assignment can benefit substantially from incorporating external variables that associate with the latent class variable. Especially when the difference in probability structure between the latent classes becomes smaller, or, when the sample size is relatively small.

Extreme Response Style and Faking: Two Sides of the Same Coin?
Using Mixed Rasch Models, several studies identified two distinct classes present in personality test data collected under lowstakes (i.e. the test person has nothing to gain or lose based on the test results) and anonymous conditions. Based on threshold diagrams the classes were interpreted as two response styles – extreme response style and midpoint responding. Within psychological research c...

متن کاملLife-wise Language Learning Textbooks: Construction and Validation of an Emotional Abilities Scale through Rasch Modeling
Underlying the recently developed notions of applied ELT and life syllabus is the idea that language classes should give precedence to learners’ life qualities, for instance emotional intelligence (EI), over and above their language skills. By so doing, ELT is ascribed an autonomous status and ELT classes can lavish their full potentials to the learners. With that in mind, this study aimed to d...
متن کاملStatistical Inference for the Multidimensional Mixed Rasch Model
Inference in Generalized linear mixed models with multivariate random effects is often made cumbersome by the high-dimensional intractable integrals involved in the marginal likelihood. This article presents an inferential methodology based on the GEE approach. This method involves the approximations of the marginal likelihood and joint moments of the variables. It is also proposed an approxima...
متن کاملRasch Model and Its Extensions for Analysis of Aphasic Deficits in Syntactic Comprehension
Aphasia is the loss of the ability to produce and/or comprehend language, due to injury to brain areas responsible for these functions. Aphasic patients’ performance on comprehension tests has traditionally been related both to the patient’s individual ability and to the difficulty of the test questions. The natural choice for analysis of these test results is the Rasch model. It assumes that t...
