Ordinal Test Fidelity Estimated by an Item Sampling Model.

Cliff, Norman; Donoghue, John R.

Psychometrika, v57 n2 p217-36 Jun 1992

A test theory using only ordinal assumptions is presented, based on the idea that the test items are a sample from a universe of items. The sum across items of the ordinal relations for a pair of persons on the universe items is analogous to a true score. (SLD)
