  "Description": "Provides a modular end-to-end framework for dynamic risk\nprediction based on time-to-event and longitudinal data. This\nallows flexible specifications for the longitudinal and\nsurvival sub-models. The 'landmaRk' package enables\nreproducible benchmarks of different model choices, including\ncross-validation to assess out-of-sample predictive\nperformance. Methods are described in Velasco-Pardo, et al.\n(2026) <arXiv:2606.24678>.",
