Tree-based methods for length-biased survival data (opens in new tab)

Left-truncated survival data commonly arise in prevalent cohort studies, where only individuals who have experienced disease onset and survived until enrollment in the study. When the onset process follows a stationary Poisson process, the resulting data are length-biased. This sampling mechanism induces a selection bias towards longer survival individuals, and statistical methods for traditional survival data are not directly applicable. Wh...
