In mlr3proba: Probabilistic Supervised Learning for 'mlr3'

Survival Task Generator for Package 'simsurv'

Description

A mlr3::TaskGenerator calling simsurv::simsurv() from package simsurv.

This generator currently only exposes a small subset of the flexibility of simsurv, and just creates a small data set with the following numerical covariates:

• treatment: Bernoulli distributed with log hazard ratio -0.5.

• height: Normally distributed with log hazard ratio 1.

• weight: normally distributed with log hazard ratio 0.

See simsurv::simsurv() for an explanation of the hyperparameters.

Dictionary

This TaskGenerator can be instantiated via the dictionary mlr_task_generators or with the associated sugar function tgen():

mlr_task_generators$get("simsurv")
tgen("simsurv")
