Test Format and Local Dependence of Items Revisited: A Case of Two Vocabulary Levels Tests. [PDF]

open access: yesFront Psychol, 2021
Local item dependence (LID) is one of the most critical assumption in the Rasch model when it comes to the validity of a test. As the field of vocabulary assessment is calling for more clarity and validity for vocabulary tests, such assumption becomes ...

Large-scale estimation of random graph models with local dependence. [PDF]

open access: yesComput Stat Data Anal, 2020
A class of random graph models is considered, combining features of exponential-family models and latent structure models, with the goal of retaining the strengths of both of them while reducing the weaknesses of each of them.

Are Exam Questions Known in Advance? Using Local Dependence to Detect Cheating. [PDF]

open access: yesPLoS ONE, 2016
Cheating is a common phenomenon in high stakes admission, licensing and university exams and threatens their validity. To detect if some exam questions had been affected by cheating, we simulated how data would look like if some test takers possessed ...

Normal approximation under local dependence [PDF]

open access: yes, 2004
We establish both uniform and nonuniform error bounds of the Berry-Esseen type in normal approximation under local dependence. These results are of an order close to the best possible if not best possible.

Unique Variable Analysis: A Network Psychometrics Method to Detect Local Dependence

open access: yesMultivariate Behavioral Research, 2023
The local independence assumption states that variables are unrelated after conditioning on a latent variable. Common problems that arise from violations of this assumption include model misspecification, biased model parameters, and inaccurate estimates

The Unit Testlet Dilemma: PISA Sample

open access: yesInternational Journal of Assessment Tools in Education, 2021
Testlets have advantages such as making it possible to measure higher-order thinking skills and saving time, which are accepted in the literature. For this reason, they have often been preferred in many implementations from in-class assessments to large ...

Item parameter recovery via traditional 2PL, Testlet and Bi-factor models for Testlet-Based tests

open access: yesInternational Journal of Assessment Tools in Education, 2022
The testlet comprises a set of items based on a common stimulus. When the testlet is used in the tests, there may violate the local independence assumption, and in this case, it would not be appropriate to use traditional item response theory models in ...
