I have been reading about Bayesian methods for performing survival analysis. One of the things that strikes me is that in the three or so books that I have read, there has been no mention of handing ties, e.g. Efron, Breslow, or exact.

Is this complication limited to frequentist statistical treatments?

  • $\begingroup$ Ties also affect Bayesian inference. The presence of ties in a sample may preclude the existence of the posterior distribution even under the use of proper priors (see). $\endgroup$ – user10525 Nov 27 '12 at 9:43
