Investigations of parameter invariance in IRT models : theoretical and pratical avenues for understanding a fundamental property of measurement
The quest for invariance is the quest for scientific generalizability and parameter invariance is thus a fundamental property of measurement that is of interest to both theoreticians and practitioners. To investigate invariance properly, a precise mathematical definition is required, which contra...
