High performance parallel Gibbs sampling for IRT models
• Item Response Theory (IRT) yields models that describe a probabilistic relationship between correct responses on a set of items and a latent trait. • We can apply Gibbs sampling to the two-parameter normal model, however a large number of iterations is needed for the Markov chain to converge. • So, the algorithm is computationally intensive and demands significant execution time. • This fact ...
متن کاملA High Performance Gibbs Sampling Algorithm for Item Response Theory
Item response theory (IRT) is a modern test theory that has been used in various aspects of educational and psychological measurement. The fully Bayesian approach shows promise for estimating IRT models. Given that it is computationally expensive, the procedure is limited in real applications. It is hence important to seek ways to reduce the execution time, and therefore, a suitable solution is...
متن کاملGenome-wide Regression & Prediction with the BGLR statistical package
Many modern genomic data analysis require implementing regressions where the number of parameters (p, e.g., the number of marker effects) exceeds sample size (n). Implementing these large-p-with-small-n regressions poses several statistical and computational challenges, some of which can be confronted using Bayesian methods. This approach allows integrating various parametric and non-parametric...
متن کاملAn Introduction to the DA-T Gibbs Sampler for the Two-Parameter Logistic (2PL) Model and Beyond
The DA-T Gibbs sampler is proposed by Maris and Maris (2002) as a Bayesian estimation method for a wide variety of Item Response Theory (IRT) models. The present paper provides an expository account of the DAT Gibbs sampler for the 2PL model. However, the scope is not limited to the 2PL model. It is demonstrated how the DA-T Gibbs sampler for the 2PL may be used to build, quite easily, Gibbs sa...
متن کاملApplication of Bayesian inference using Gibbs sampling to item-response theory modeling of multi-symptom genetic data.
Several "genetic" item-response theory (IRT) models are fitted to the responses of 1086 adolescent female twins to the 33 multi-category item Mood and Feeling Questionnaire relating to depressive symptomatology in adolescence. A Markov-chain Monte Carlo (MCMC) algorithm is used within a Bayesian framework for inference using Gibbs sampling, implemented in the program WinBUGS 1.4. The final mode...
