  "Description": "A latent, quasi-independent truncation time is assumed to\nbe linked with the observed dependent truncation time, the\nevent time, and an unknown transformation parameter via a\nstructural transformation model. The transformation parameter\nis chosen to minimize the conditional Kendall's tau (Martin and\nBetensky, 2005) <doi:10.1198/016214504000001538> or the\nregression coefficient estimates (Jones and Crowley, 1992)\n<doi:10.2307/2336782>. The marginal distribution for the\ntruncation time and the event time are completely left\nunspecified. The methodology is applied to survival curve\nestimation and regression analysis.",
