Use this skill whenever the outcome is right-censored time-to-event data, including progression, conversion, relapse, hospitalization, or mortality prediction. It supports Cox proportional hazards, Random Survival Forest, DeepSurv, and XGBoost Cox survival with censor-aware cross-validation. Triggers include 'survival analysis', 'time to event', 'censored outcome', 'Cox model', 'hazard ratio', 'Random Survival Forest', 'DeepSurv', 'XGBoost survival', 'progression', and 'conversion risk'.
