Assumptions and Likelihoods in More Detail

A.1 Notation Let T be a failure time with CDFF. T's survival function is defined by F = 1 F. We denote failure models by FθT. Let C be a censoring time with CDFG, survival function G, and model GθC. Under right-censoring, define U = min(T,C), = 1 [T C] and we observe (Xi,Ui, i). We use G(t) to denote P(C t).
