Struct Ratio 

pub struct Ratio {
    pub point: f64,
    pub lcb95: Option<f64>,
    pub method: RatioMethod,
    pub n: usize,
}

P-5 — one metric’s ratio, with the bound the verdict is taken on.

point is x_subject / x_comparator. lcb95 is the one-sided 95% lower confidence bound; None means the design could not support one and the ratio is REPORTING only.

Fields

point: f64

The ratio on the observed data.

lcb95: Option<f64>

One-sided 95% lower bound, or None when the design cannot support one.

method: RatioMethod

Which estimator produced it.

n: usize

Observations the estimator used — replicates or requests, per method.

Implementations

impl Ratio

pub fn reporting_only(point: f64, method: RatioMethod, n: usize) -> Self

A ratio with no bound, for a design that cannot support one (n < 5 replicates). REPORTING only: P-5’s verdict needs lcb95.

pub fn passes(&self, delta: f64) -> bool

P-5 — does this ratio PASS at non-inferiority margin delta?

false when there is no bound: a ratio without a lower bound has not been shown to be anything, and “no evidence” is not a pass.
