Modified Bayesian Information Criterion for Item Response Models in Planned Missingness Test Designs

Analytics
The Bayesian information criterion (BIC) is a widely used statistical tool originally derived for fully observed data. The BIC formula includes the sample size and the number of estimated parameters in the penalty term.

Group Two-Phase Locking: A Scalable Data Sharing Protocol

, 2007
this paper, we examine and compare the scalability of the server-based two-phase locking protocol (s-2PL), and the group two-phase locking protocol (g-2PL). The s-2PL protocol is the most widely used concurrency control protocol, while the g-2PL protocol

Item response theory-based continuous norming

In norm-referenced psychological testing, an individual’s performance is expressed in relation to a reference population using a standardized score, like an intelligence quotient score.

Detecting DIF in 2PL Multistage Assessments Advanced Senior Scientist and Research Group Leader Senior Researcher in Statistical Modeling Research Associate Phd Student Statistical Consulant

The detection of differential item functioning is crucial for the psychometric evaluation of multistage tests. This paper discusses five approaches presented in the literature: Logistic regression, SIBTEST, analytical score-based tests, Bootstrap score-based tests and permutation score-based tests.

When Alpha Fails: Jouve's Randomized Reliability Estimation (ξ) versus Classical Reliability Coefficients in Rasch, 2PL, 3PL, 4PL, GRM, GPCM, and NRM Models

We present a comprehensive simulation study comparing Jouve's Randomized Reliability Estimation (JRRE, denoted ξ) to classical reliability coefficients—Cronbach's α, KR-20, McDonald's ω_t, eigenvalue-based lower bounds (EVLB), and Guttman's λ coefficients—across diverse item response theory (IRT) models and realistic data conditions.
