Estimating Diffusion-Based Item Response Theory Models: Exploring the Robustness of Three Old and Two New Estimators

Diffusion-based item response theory models for responses and response times in tests have attracted increased attention recently in psychometrics. Analyzing response time data, however, is delicate as response times are often contaminated by unusual observations. This can have serious effects on th...
