Implementation Aspects in Simulation Extrapolation-Based Stocking–Lord Linking

Applied Sciences
Stocking–Lord (SL) linking is commonly used for group comparisons based on dichotomous item responses. Recently, the simulation extrapolation (SIMEX) method for SL linking has been introduced within the two-parameter logistic (2PL) model to reduce the ...

Comparing Weighted RMSD, Weighted MD, Infit, and Outfit Item Fit Statistics Under Uniform Differential Item Functioning

Mathematics
In educational large-scale assessment studies, uniform differential item functioning (DIF) across countries often challenges the application of a common item response model, such as the two-parameter logistic (2PL) model, to all participating countries ...

Bias-Reduced Haebara and Stocking–Lord Linking

J
Haebara and Stocking–Lord linking methods are frequently used to compare the distributions of two groups. Previous research has demonstrated that Haebara and Stocking–Lord linking can produce bias in estimated standard deviations and, to a smaller extent,

Analytical modeling of lock-based concurrency control with arbitrary transaction data access patterns

, 2010
Nowadays the 2-Phase-Locking (2PL) concurrency control algorithm still plays a core rule in the construction of transactional systems (e.g. database systems and transactional memories).
