Bayesian Analysis of a Quantile Multilevel Item Response Theory Model

open access: yesFrontiers in Psychology, 2021
Multilevel item response theory (MLIRT) models are used widely in educational and psychological research. This type of modeling has two or more levels, including an item response theory model as the measurement part and a linear-regression model as the ...

Explanatory Item Response Models for Polytomous Item Responses

open access: yesInternational Journal of Assessment Tools in Education, 2019
Item response theory is a widely used framework for the design, scoring, and scaling of measurement instruments. Item response models are typically used for dichotomously scored questions that have only two score points (e.g., multiple-choice items).

Item Response Analysis of a Structured Mixture Item Response Model with mirt Package in R

open access: yesPsych
Structured mixture item response models (StrMixIRMs) are a special type of constrained confirmatory mixture item response theory (IRT) model for detecting latent performance differences in a measurement instrument by characteristic item groups, and ...

Inverse transformed encoding models - A solution to the problem of correlated trial-by-trial parameter estimates in fMRI decoding [PDF]

open access: yes, 2019
Techniques of multivariate pattern analysis (MVPA) can be used to decode the discrete experimental condition or a continuous modulator variable from measured brain activity during a particular trial. In functional magnetic resonance imaging (fMRI), trial-

Bias-Corrected Root Mean Square Deviation Estimators

open access: yesFoundations
The root mean square deviation (RMSD) is a widely used item fit statistic in item response models. However, the sample RMSD is known to exhibit positive bias in small samples. To address this, seven alternative bias-corrected RMSD estimators are proposed
