A model for variability in arteriographic reading.
We propose a class of models for the joint cumulative distribution function (c.d.f.) of the values of two independent readings of percentage stenosis from a coronary arteriography. We show that these models are identifiable and that a certain subclass has unique consistent estimators for the parameters in question. We obtain these estimates for a data set from a substudy of the Coronary Artery Surgery Study (CASS).
