The design a time-to-event case study is primarily simulated under

No control-arm heterogeneity, no loss to follow-up, exponential event times and proportional hazards (no delay before the treatment effect). It is the design a configuration that does not mention the sensitivity axes produces, and the one the whole scenario grid is simulated at.

Usage

is_primary_time_to_event_design(
  control_drift,
  dropout_probability,
  event_time_distribution,
  treatment_delay = 0
)

Arguments

control_drift

Control-arm heterogeneity, kappa.

dropout_probability

Probability of loss to follow-up over the maximum follow-up time.

event_time_distribution

Either "exponential" or "weibull".

treatment_delay

Time before the treatment effect starts, in years.

Value

TRUE when the four describe the primary design.
