• 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.

Format

R6::R6Class inheriting from mlr3::TaskGenerator.
