melanoma

datasets

Fits a non-linear transformation model ('nltm') for
analyzing survival data, see Tsodikov (2003) <doi:10.1111/1467-9868.00414>. The
class of 'nltm' includes the following currently supported
models: Cox proportional hazard, proportional hazard cure,
proportional odds, proportional hazard - proportional hazard
cure, proportional hazard - proportional odds cure, Gamma
frailty, and proportional hazard - proportional odds.
