Struct SurvfuncRight 

pub struct SurvfuncRight {
    pub surv_times: Array1<f64>,
    pub surv_prob: Array1<f64>,
    pub surv_prob_se: Array1<f64>,
    pub n_risk: Array1<f64>,
    pub n_events: Array1<f64>,
}

The Kaplan–Meier estimate of a right-censored survival function.

Construct with SurvfuncRight::new, passing observation times and a status indicator (1.0 = event/failure observed, 0.0 = right-censored).

Fields

surv_times: Array1<f64>

Distinct event times, ascending. Only times with at least one failure.

surv_prob: Array1<f64>

The product-limit survival probability S(t) at each event time.

surv_prob_se: Array1<f64>

Greenwood standard error of S(t) at each event time (NaN where the risk set is exhausted, i.e. n == d).

n_risk: Array1<f64>

Size of the risk set just prior to each event time.

n_events: Array1<f64>

Number of events (failures) at each event time.

Implementations

impl SurvfuncRight

pub fn new(time: &[f64], status: &[f64]) -> Result<Self>

Estimate the survival function from right-censored data.

time and status must have equal length. status[i] is treated as an event when it rounds to 1 and as censoring otherwise.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SurvfuncRight

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
