Local Dependence in Random Graph Models: Characterization, Properties and Statistical Inference [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2015
Dependent phenomena, such as relational, spatial and temporal phenomena, tend to be characterized by local dependence in the sense that units which are close in a well‐defined sense are dependent.

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

open access: yesFront Psychol, 2022
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.

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

Copula-based local dependence among energy, agriculture and metal commodities markets

open access: yesEnergy, 2020
This paper studies the extreme dependencies among energy, agriculture and metal commodities markets, with an emphasis on local co-movements. By applying a novel, copula-based, local Kendall's tau approach to measure nonlinear local dependence in regions,

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 ...

Local Dependence in Latent Class Analysis of Rare and Sensitive Events [PDF]

open access: yesSociol Methods Res, 2013
For survey methodologists, latent class analysis (LCA) is a powerful tool for assessing the measurement error in survey questions, evaluating survey methods, and estimating the bias in estimates of population prevalence.

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 ...
