Struct PeriodSummary

Source

pub struct PeriodSummary<K> {
    pub period: Option<K>,
    pub n: usize,
    pub weight: f64,
    pub actual: f64,
    pub expected: f64,
    pub std_dev: f64,
}

Expand description

One period’s (or the total’s) actual against expected.

Fields§

§period: Option<K>

The period (None for the total).

§n: usize

Number of rows.

§weight: f64

Σ w: exposure or prior weight.

§actual: f64

Σ w y.

§expected: f64

Σ w μ.

§std_dev: f64

Standard deviation of A - E under the model, √(φ Σ w V(μ)).

Implementations§

Source §

impl<K> PeriodSummary<K>

Source

pub fn ratio(&self) -> f64

actual / expected.

Source

pub fn z(&self) -> f64

(A - E) / std_dev: about standard normal when the model holds; beyond ±2 or ±3 is worth a look.
