The Geometry of Probability, Statistics, and Test Theory.
Zimmerman, Donald W.; Zumbo, Bruno D.
International Journal of Testing, v1 n3&4 p283-303 2001
Presents a model of tests and measurement that identifies test scores with Hilbert space vectors and true and error components of scores with linear operators. This geometric point of view brings to light relations among elementary concepts in test theory, including reliability, validity, and parallel tests. (Author/SLD)
