WebThis article discusses the assumptions required by the item response theory (IRT) true-score equating method (with Stocking & Lord, 1983; scaling approach), which is commonly used … WebIRT has been developed in interaction with two other statistical areas of response modeling. The first is the area of bioassay with its models for data on the biological responses of organisms exposed to varying doses of a chemical substance.
