Bayesian Estimation of the Logistic Positive Exponent IRT Model
(SAGE PUBLICATIONS INC, 2010)
A Bayesian inference approach using Markov Chain Monte Carlo (MCMC) is developed for the logistic positive exponent (LPE) model proposed by Samejima and for a new skewed Logistic Item Response Theory (IRT) model, named ...

Obsession with Covid-19 in Peruvian police and armed forces: Validation of the obsession with Covid-19 Scale in Spanish using SEM and IRT models
(Routledge, 2021-01-01)
The study evaluated the psychometric properties of the Spanish version of the Obsession with COVID-19 Scale (OCS) in 214 police and members of the armed forces (M age = 29.33 years, SD = 11.28). The one-dimensionality and ...
Infrared Thermography technique (IRT) for the evaluation of the hydric behavior of building stones
(IMEKO-ACTA, 2018-10)
The water distribution into stone specimens in laboratory conditions is evaluated through the infrared thermography method (IRT). Porous building stones samples (calcarenite and sandstone) are examined under stable laboratory ...
Possible Factors Which May Impact Kernel Equating of Mixed-Format Tests
(Springer Cham, 2021)
Mixed-format tests contain items with different formats such as dichotomously scored and polytomously scored items. The aim of this study was to examine the impact of item discrimination, sample size, and proportion of ...
Evaluation of the Computer-based Battery for Oral Language (BILOv3) through the Rasch model for a Brazilian Sample
There are few tests in Brazil to evaluate the comprehension of oral language, especially the ones that are computer-based. Thus, this study aimed at investigating psychometric characteristics for a computer-based battery ...

How Often Is the Misfit of Item Response Theory Models Practically Significant?
(National Council on Measurement in Education, 2014)
Standard 3.9 of the Standards for Educational and Psychological Testing (1999) demands evidence of model fit when item response theory (IRT) models are employed to data from tests. Hambleton and Han (2005) and Sinharay ...
