Local item dependence on the vocabulary levels test revisited

open access: yesVocabulary Learning and Instruction, 2014
The purpose of this study was to address the question of local item dependence (LID) on the Vocabulary Levels Test (VLT). The test format adopts a matching format consisting of six words and three definitions.

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

open access: yesApplied 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

Feature Selection based on the Local Lift Dependence Scale

open access: yesEntropy, 2018
This paper uses a classical approach to feature selection: minimization of a cost function applied on estimated joint distributions. However, in this new formulation, the optimization search space is extended.

Detecting the influence of item chaining on student responses to the Force Concept Inventory and the Force and Motion Conceptual Evaluation

open access: yesPhysical Review Physics Education Research, 2020
Items that are chained, or blocked, together appear on many of the conceptual assessments utilized for physics education research. However, when items are chained together there is the potential to introduce local dependence between those items, which ...

Equivalence and bifurcations of finite order stochastic processes [PDF]

open access: yes, 2005
This article presents an equivalence notion of finite order stochastic processes. Local dependence measures are defined in terms of ratios of joint and marginal probability densities.

A Comparison of Limited Information Estimation Methods for the Two-Parameter Normal-Ogive Model with Locally Dependent Items

open access: yesStats
The two-parameter normal-ogive (2PNO) model is one of the most popular item response theory (IRT) models for analyzing dichotomous items. Consistent parameter estimation of the 2PNO model using marginal maximum likelihood estimation relies on the local ...

Hierarchical watermarking depending on local constraints [PDF]

open access: yesProceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
We propose a new watermarking technique where the watermark is embedded according to two keys. The first key is used to embed a code bit in a block of pixels. The second is used to generate the whole sequence of code bits The watermark is embedded in spatial domain by adding or subtracting a random digital pattern to the given image signal.

Attribute Reduction Method of Covering Rough Set Based on Dependence Degree

open access: yesInternational Journal of Computational Intelligence Systems, 2021
Attribute reduction is a hot topic in the field of data mining. Compared with the traditional methods, the attribute reduction algorithm based on covering rough set is more suitable for dealing with numerical data.
