Linking Error in the 2PL Model

J, 2023
The two-parameter logistic (2PL) item response model is likely the most frequently applied item response model for analyzing dichotomous data. Linking errors quantify the variability in means or standard deviations due to the choice of items.

Pairwise Likelihood Estimation of the 2PL Model with Locally Dependent Item Responses

Applied Sciences
The local independence assumption is crucial for the consistent estimation of item parameters in item response theory models. This article explores a pairwise likelihood estimation approach for the two-parameter logistic (2PL) model that treats the local

The Rank-2PL IRT Models for Forced-Choice Questionnaires: Maximum Marginal Likelihood Estimation with an EM Algorithm. [PDF]

J Educ Behav Stat
The rank two-parameter logistic (Rank-2PL) item response theory models refer to a set of models applying the 2PL model in a sequential ranking process that occurs in forced-choice questionnaires. The multi-unidimensional pairwise preference with 2PL model (MUPP-2PL) is a Rank-2PL model for items with two statements.

AN ELEMENTARY TEST OF THE NORMAL 2PL MODEL AGAINST THE NORMAL 3PL ALTERNATIVE [PDF]

ETS Research Report Series, 2006
ABSTRACTA simple score test of the normal two‐parameter logistic (2PL) model is presented that examines the potential attraction of the normal three‐parameter logistic (3PL) model for use with a particular item. Application is made to data from a test from the Praxis™ series.

Psychometric validation of the informed consent assessment scale using item response theory and factor analysis [PDF]

Frontiers in Medicine
ObjectivesInformed consent is a central ethical and legal practice in medicine, yet communication skills specific to this task are under-assessed in undergraduate medical education. This study aimed to develop and validate the informed consent assessment

Item and Test Characteristic Curves of Rank-2PL Models for Multidimensional Forced-Choice Questionnaires. [PDF]

Appl Meas Educ
A process is proposed to create the one-dimensional expected item characteristic curve (ICC) and test characteristic curve (TCC) for each trait in multidimensional forced-choice questionnaires based on the Rank-2PL (two-parameter logistic) item response theory models for forced-choice items with two or three statements.

Comparing Robust Linking and Regularized Estimation for Linking Two Groups in the 1PL and 2PL Models in the Presence of Sparse Uniform Differential Item Functioning

Stats, 2023
In the social sciences, the performance of two groups is frequently compared based on a cognitive test involving binary items. Item response models are often utilized for comparing the two groups. However, the presence of differential item functioning (DIF) can impact group comparisons.
