Exploring local dependence [PDF]
This paper discusses two graphical methods for the investigation of local association of two continuous random variables. Often, scalar dependence measures, such as correlation, cannot reflect the complex dependence structure of two variables.

Logics of dependence and independence: The local variants [PDF]
Abstract Modern logics of dependence and independence are based on team semantics, which means that formulae are evaluated not on a single assignment of values to variables, but on a set of such assignments, called a team. This leads to high expressive power, on the level of existential second-order logic.

The Unit Testlet Dilemma: PISA Sample
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
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 ...

Parameter Estimation of KST-IRT Model under Local Dependence
A mantra often repeated in the introductory material to psychometrics and Item Response Theory (IRT) is that a Rasch model is a probabilistic version of a Guttman scale. The idea comes from the observation that a sigmoidal item response function provides

Food Production and Consumption in Ordos of Inner Mongolia
Ordos is an ecological fragile area in the upstream and midstream of the Yellow River and a component of the ecological security barrier on the northern frontier of China. With population growth in recent years, the contradiction between human beings and

Local Dependency in Networks [PDF]
Many real world data or process eave a network structure and can usefully be represented as graphs. Network analysis focuses on the relations among the nodes exploring the properts hies of network. We introduce a method for measuring the dependency between the nodes of a network, that is based on a structure in the local surroundings of the node.
