A Series of Lower Bounds to the Reliability of a Test.
ten Berge, Jos M. F.; Zegers, Frits E.
Psychometrika, v43 n4 p575-79 Dec 1978
Two lower bounds to reliability in classical test theory, Guttman's lamda and Cronbach's alpha, are shown to be terms of an infinite series of lower bounds. All terms of this series are equal to reliability if and only if the test contains items which are tau-equivalent. (Author/JKS)
