Jmg. Taylor et al., NORMAL RANGE ESTIMATION FOR REPEATED IMMUNOLOGICAL MEASURES, Clinical and diagnostic laboratory immunology, 3(2), 1996, pp. 139-142
A method for estimating a normal range from a set of immunologic measu
rements on control subjects when there may be more than one observatio
n per subject is described. The method is nonparametric, makes efficie
