Coefficients for Tests from a Decision Theoretic Point of View
Vander Linden, Wim J.; Mellenbergh, Gideon J.
Applied Psychological Measurement, 2, 1, 119-34, W 78
A general coefficient for tests, delta, is derived from a decision theoretic point of view. The situations are considered in which a true score is estimated by a function of the observed score, observed scores are split into more than two categories, and observed scores are split into only two categories.
