A LearnerSurv for a Flexible Parametric Spline model partially implemented in flexsurv::flexsurvspline() in package flexsurv.

Format

R6::R6Class inheriting from LearnerSurv.

Details

The predict method is based on flexsurv::summary.flexsurvreg() but adapts the return type to be compatible with distr6.

Construction

LearnerSurvFlexible$new() mlr_learners$get("surv.flexible")
lrn("surv.flexible")
