A Generalization of the Intraclass Tau Correlation for Tied and Censored Data
MICHAEL SCHEMPER · Biometrical Journal · 1984
Abstract Intraclass tau correlations and a corresponding asymptotic permutation test have already been derived by WHITFIELD (1949), though for continuous data only. WHITFIELD'S concepts are now generalized for use with tied and censored data and a suggestion is made for the application of the methods to arbitrary and varying group sizes. Special attention is given to their application to dichotomous data. Extensive simulations confirming the safe use of the asymptotic test even for samples of moderate size are reported and calculated examples with data from twin‐births and kidney transplantations presented.
