Changelog
heemod 1.0.0
Breaking changes
- dplyr’s pipe now causes an error when chaining survival operation. The new pipe |> is required in this situation.
define_survival()

define_surv_fit()
to specify a survival fit created with survfit()
, flexsurvreg()
or flexsurvspline()
New Features
- It is now possible to run probabilistic sensitivity analysis (PSA) with survival objects - either created from a parametric distribution (with
