Automated Essay Scoring Effect on Test Equating Errors in Mixed-format Test
International Journal of Assessment Tools in Education, 2021 Scoring constructed-response items can be highly difficult, time-consuming, and costly in practice. Improvements in computer technology have enabled automated scoring of constructed-response items. However, the application of automated scoring without an

Rheumatoid arthritis, item response theory, Blom transformation, and mixed models [PDF]
BMC Proceedings, 2007 We studied rheumatoid arthritis (RA) in the North American Rheumatoid Arthritis Consortium (NARAC) data (1499 subjects; 757 families). Identical methods were applied for studying RA in the Genetic Analysis Workshop 15 (GAW15) simulated data (with a prior knowledge of the simulation answers).
