Find, download, and analyze datasets from the Item Response Warehouse, a harmonized collection of item response data from educational and psychological measurement described in Nadela et al. (2026) <doi:10.59863/cijg4549>. Functions search tables by metadata, fetch them in a common long format, reshape between long and wide layouts, simulate item response data, and compare the predictive accuracy of fitted models with the InterModel Vigorish.
