Higher dimensional Clayton–Oakes models for multivariate failure time data

R. L. Prentice.

in Biometrika

March 2016; p ublished online December 2015 .

Journal Article. Subjects: Biomathematics and Statistics; Probability and Statistics. 2639 words.

The Clayton–Oakes bivariate failure time model is extended to dimensions [math] in a manner that allows unspecified marginal survivor functions for all dimensions less than [math]. Special...
