A class of general tests for testing independence of failure time and cause of failure in a competing risks model
P. G. Sankaran, Isha Dewan and E. P. Sreedevi
In this paper we introduce a class of tests for testing independence of failure time and cause of failure for competing risks data. A class of tests using martingale approach is derived. We, then develop a test statistic using likelihood ratio procedure. Asymptotic distributions of the proposed test statistics are derived. The procedures are illustrated using a real life example. A simulation study is carried out to assess the power of the tests.
