Survival Trees to Fit Left-Truncated and Right-Censored and Interval-Censored Survival Data R package LTRCtrees version 1.1.2 CRAN Task View: Survival (https://CRAN.R-project.org/view=Survival) Recursive partition algorithms designed for fitting survival trees with left-truncated and right-censored (LTRC) data, as well as interval-censored data. The LTRC trees can also be used to fit survival trees with time-varying covariates.
