Bias-Reduced Haebara and Stocking–Lord Linking

open access: yesJ
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,

An optimized Bayesian hierarchical two-parameter logistic model for small-sample item calibration

open access: yes, 2019
Accurate item calibration in models of item response theory (IRT) requires rather large samples. For instance, [Formula: see text] respondents are typically recommended for the two-parameter logistic (2PL) model.

Bias Reduction in Robust Mean–Geometric Mean Linking via SIMEX

open access: yesAlgorithms
Robust mean–geometric mean (MGM) linking is a method for comparing the performance of two groups on a test involving dichotomous items and is particularly suited to settings with fixed and sparse differential item functioning (DIF).

Concurrency control model based on distributed high priority two phase locking for distributed real-time database system

open access: yes, 2004
介绍了几种用于RTDBS(实时数据库系统)中的并发控制模型以及它们在分布式环境下(DRTDBS)的拓展。根据DHP-2PL提出一种改进的并发控制模型。在该模型中,引入优先级分配机制和加锁检测机制。通过这两种机制可更好地协调DRTDBS中一致性与截止期的关系,同时也解决了DHP-2PL中事务高重启率的问题。Some concurrency control models used for RTDBS were introduced, and how to use them on the ...

Linking Error Estimation in Haberman Linking

open access: yesAppliedMath
Haberman linking is a widely used method for comparing groups using the two-parameter logistic item response model. However, the traditional Haberman linking approach relies on joint item parameter estimation, which prevents the application of standard M-

Detection of latent differential item functioning (DIF) using mixture 2PL IRT model with covariate [PDF]

open access: yes, 2017
Mixture IRT models have been shown to improve the identification of latent group structure and facilitate the estimation of model parameters when covariates are incorporated or the Bayesian estimation method is employed.
