Tuning Parameters

#| label: flexsurv-param-info
#| echo: false
defaults <- 
  tibble::tibble(parsnip = c("dist"),
                 default = c("'weibull'"))

param <-
  survival_reg() |>
  set_engine("flexsurv") |>
  set_mode("censored regression") |>
  make_parameter_list(defaults)

This model has r nrow(param) tuning parameters:

Translation from parsnip to the original package

Other details

The main interface for this model uses the formula method since the model specification typically involved the use of [survival::Surv()].

For this engine, stratification cannot be specified via [survival::strata()], please see [flexsurv::flexsurvreg()] for alternative specifications.
