Fitted models\nreturn landmark risk predictions over user-specified horizons\nwith posterior or bootstrap uncertainty by evaluating survival\nratios across fitted hazard draws. Utilities are provided for\nsimulation, staged model fitting, plotting and summarising\ndynamic risk curves, IPCW Brier scores, cumulative/dynamic\ntime-dependent area under the curve, calibration tables, and an\nanonymised chronic myeloid leukaemia molecular-monitoring\nexample data set.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Language": "en-US", "LazyData": "true",
