Over the decades, testing for equivalence of hazard functions has received a wide
attention in survival analysis. In this paper, we proposed a Bayesian test to
address this testing equivalence problem, Most of all, proposed test is
methodologically flexible so that a procedure determining weights is not required
when the proportional assumption is violated. In comparison with popularly
exploited methods, the proposed test is shown to be more powerful and robust in
testing differences of hazard functions, in spite of the presence of crossing
hazard functions. Extensive applications to simulation and real data were
conducted, demonstrating that the proposed test presents outstanding performance
and hold desirable properties in terms of numerical aspects.
