REWEIGHTING DATA IN THE SPIRIT OF TUKEY: USING BAYESIAN POSTERIOR PROBABILITIES AS RASCH RESIDUALS FOR STUDYING MISFIT [PDF]

open access: yes, 2010
A new variant of the iterative "data = fit + residual" data-analytical approach described by Mosteller and Tukey is proposed and implemented in the context of item response theory psychometric models.

Latent Transition Analysis With a Mixture Item Response Theory Measurement Model

open access: yes, 2010
A latent transition analysis (LTA) model was described with a mixture Rasch model (MRM) as the measurement model. Unlike the LTA, which was developed with a latent class measurement model, the LTA-MRM permits within-class variability on the latent ...

Assessing Robustness of the Rasch Mixture Model to Detect Differential Item Functioning - A Monte Carlo Simulation Study

open access: yes, 2020
Measurement invariance is crucial for an effective and valid measure of a construct. Invariance holds when the latent trait varies consistently across subgroups; in other words, the mean differences among subgroups are only due to true latent ability ...

THE MIXTURE DISTRIBUTION POLYTOMOUS RASCH MODEL USED TO ACCOUNT FOR RESPONSE STYLES ON RATING SCALES: A SIMULATION STUDY OF PARAMETER RECOVERY AND CLASSIFICATION ACCURACY [PDF]

open access: yes, 2013
Response styles presented in rating scale use have been recognized as an important source of systematic measurement bias in self-report assessment. People with the same amount of a latent trait may be a victim of a biased test score due to the construct ...

A mixture IRT growth model for longitudinal data from e-learning environments

open access: yes, 2013
This poster describes a generalized longitudinal mixture item response theory (IRT) model that allows for detecting latent group differences for item response data obtained from electronic learning (e-learning) environments or other environments that ...

Typology of Ideal Personality: Applicant Perspective In Job Selection Setting [PDF]

open access: yes, 2012
Previously studies suggest that job applicant fake response on a personality test based on their stereotype of ideal employee. This study explored typology of personality that relied on applicants’ stereotype.
