Usage

project_soc_only(
  data,
  time = "time",
  event = "event",
  subgroup = NULL,
  arm = NULL,
  soc_level = "SOC",
  tau = NULL,
  landmark_times = NULL,
  hr_scenarios = c(0.7, 0.85, 1),
  target_delta_rmst = NULL,
  prior_mean_log_hr = NULL,
  prior_sd_log_hr = NULL,
  prior_draws = 2000L,
  bootstrap = 0L,
  seed = 1L,
  n_grid = 100L
)

Arguments

data: Analysis-ready data frame.
time, event: Column names identifying follow-up and event status.
subgroup: Optional subgroup column name.
arm: Optional treatment column. When supplied, only rows matching soc_level are retained before projection.
soc_level: Reference level used when arm is supplied.
tau: RMST truncation horizon.
landmark_times: Survival-difference time points.
hr_scenarios: Numeric vector of proportional-hazard multipliers.
target_delta_rmst: Optional target RMST gain used to reverse-solve required_hr.
prior_mean_log_hr, prior_sd_log_hr: Optional normal prior parameters for the log hazard ratio. When both are supplied alongside target_delta_rmst, a PoS proxy is reported.
prior_draws: Number of Monte Carlo draws for the PoS proxy.
bootstrap: Number of bootstrap resamples used to derive intervals.
seed: Random seed.
n_grid: Number of time points used to summarize curves.

Value

An object of class cce_soc_result.
