Details

This example has been replicated a number of times (e.g., Hunter & Schmidt, 2004). It is useful in illustrating the basic concepts of validity generalization. The data can be used to demonstrate bare-bones MA as well as correction for artifacts. This data format is the format necessary for the R functions in the psychometric package.
