A mixture Rasch facets model for rater’s illusory halo effects [PDF]
A rater's overall impression of a ratee's essay (or other assessment) can influence ratings on multiple criteria to yield excessively similar ratings (halo effect). However, existing analytic methods fail to identify whether similar ratings stem from homogeneous criteria (true halo) or rater bias (illusory halo).

Flexible Rasch Mixture Models with Packagepsychomix [PDF]
Measurement invariance is an important assumption in the Rasch model and mixture models constitute a flexible way of checking for a violation of this assumption by detecting unobserved heterogeneity in item response data. Here, a general class of Rasch mixture models is established and implemented in R, using conditional maximum likelihood estimation ...

Strong Gaussian approximation of the mixture Rasch model [PDF]
We consider the famous Rasch model, which is applied to psychometric surveys when n persons under test answer m questions. The score is given by a realization of a random binary (n,m)-matrix. Its (j,k)th component indicates whether or not the answer of the jth person to the kth question is correct.

Rasch Mixture Models for DIF Detection [PDF]
Rasch mixture models can be a useful tool when checking the assumption of measurement invariance for a single Rasch model. They provide advantages compared to manifest differential item functioning (DIF) tests when the DIF groups are only weakly correlated with the manifest covariates available.

Statistical inference on group Rasch mixture network models
In a two‐mode network, the nodes are divided into two types (primary nodes and secondary nodes), and connections exist only between nodes of different types. In reality, in such a two‐mode network, one‐mode network connections may also exist among primary nodes, and these two kinds of networks are usually not independent and coexistent.

This study aimed to test the reliability and validity of the Indonesian-translated Body Regulation Exercise Questionnaire (BREQ-3), originally developed by Wilson et al. (2006), using Rasch analysis. A total of 408 Indonesian participants aged 18–25 years completed the survey. The results supported the unidimensionality of each BREQ-3 subscale.

A survey of unidimensional, multidimensional, and mixture distribution Rasch models is presented with a particular focus on model applications for the analysis of change in repeated measures designs. A mover-stayer mixed Rasch model is specified for modeling global change in one of two latent subpopulations and for modeling stability in the other ...

Rational numbers and proportional reasoning are challenging topics in school mathematics. Though much research has been conducted, the learning of these topics is rarely explored among learners taught by expert teachers.

Abstract Few studies have examined birth order effects on personality in countries that are not Western, educated, industrialized, rich, and democratic (WEIRD). However, theories have generally suggested that interculturally universal family dynamics are the mechanism behind birth order effects, and prominent theories such as resource dilution would ...
