Generate Data for a DataSimObject

Generate Data for a DataSimObject

Usage

# S4 method for class 'DataSimObject'
generate(x, n = 1, treatment_hr = NULL, drift_hr = NULL)

Arguments

x

a DataSimObject object created by create_data_simulation

n

number of data sets to simulate

treatment_hr

vector of numeric treatment effects

drift_hr

vector of numeric drift effects

Value

A SimDataList object for use with create_simulation_obj().

Examples

baseline_obj <- create_baseline_object(
  n_trt_int = 100,
  n_ctrl_int = 50,
  n_ctrl_ext = 10,
  covariates = baseline_covariates(
    names = c("age", "score"),
    means_int = c(55, 5),
    means_ext = c(60, 5),
    covariance_int = covariance_matrix(c(5, 1))
  )
)
sim_obj <- create_data_simulation(
  baseline_obj,
  coefficients = c(age = 0.001, score = 1.5),
  event_dist = create_event_dist(dist = "exponential", lambdas = 1 / 36)
)
data_sim_list <- generate(sim_obj, treatment_hr = c(0, 1), drift_hr = 0.5)
#> Warning: There were 100 event times evaluated at infinity (likely due to the hazard approaching zero). Perhaps consider specifying a finite censoring time using the 'maxt' argument.
