xxIRT: Item Response Theory

Share:

An implementation of Item Response Theory (IRT) in R, comprising of five modules:(1) common and utility functions, (2) estimation/calibration procedures, (3) computerized adaptive testing (CAT) framework, (4) automated test assembly (ATA) framework, and (5) multistage testing (MST) framework. See documentation at https://github.com/xluo11/xxIRT/blob/master/README.md.
