On the Derivation of Camp's Tetrachoric Correlation Approximation.
Rae, Gordon
Educational and Psychological Measurement, v57 n4 p631-36 Aug 1997
Although Camp's tetrachoric correlation approximation (B. Camp, 1934) has been shown to yield excellent results over a fairly wide range, its derivation remains something of a mystery. This article shows how Camp might have arrived at his formula using a theoretical, rather than an empirical, approach. (Author/SLD)
