Function survdiff

survdiff(
    time: readonly number[],
    status: readonly number[],
    group: readonly (GroupLabel | null)[],
    options?: SurvdiffOptions,
): SurvdiffResult
Test of the difference between survival curves: the G-rho family of Harrington and Fleming, the log-rank test for rho = 0. Equivalent to R's survival::survdiff(). As survdiff(Surv(time, status) ~ group, rho = rho).

Rows with a missing time, status or group are dropped.
Parameters
- time: readonly number[]
  Follow-up times.
- status: readonly number[]
  1 for an event, 0 for a censored time.
- group: readonly (GroupLabel | null)[]
  Group labels, one per observation.
- options: SurvdiffOptions = {}
  See SurvdiffOptions.
Returns SurvdiffResult
Example
```
const r = survdiff([1, 2, 3, 4, 5, 6], [1, 1, 0, 1, 1, 1], ["a", "b", "a", "b", "a", "b"]);
r.chisq;  // 0.073903
r.pvalue; // 0.78574
```
