This learner estimates the Cumulative Incidence Function (CIF) for competing risks using the empirical Aalen-Johansen (AJ) estimator. The probability of transitioning to each competing event is computed via the survfit function.

Dictionary

This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn():

LearnerCompRisksAalenJohansen$new()
mlr_learners$get("cmprsk.aalen")
lrn("cmprsk.aalen")
