Struct CusumConfig 

pub struct CusumConfig {
    pub k: f64,
    pub h: f64,
    pub ncomp: usize,
    pub alpha: f64,
    pub multivariate: bool,
    pub restart: bool,
}

Configuration for CUSUM monitoring.

Fields

k: f64

CUSUM reference value (allowance parameter, default 0.5). Controls the size of shifts the chart is designed to detect.

h: f64

CUSUM decision interval (threshold, default 5.0).

ncomp: usize

Number of principal components (default 5).

alpha: f64

Significance level for fallback chi-squared limit (default 0.05).

multivariate: bool

Whether to use multivariate CUSUM (Crosier’s MCUSUM) or per-component univariate CUSUM (default: true = multivariate).

restart: bool

Whether to restart the CUSUM accumulator after each alarm (default false). When true, the accumulator resets to zero after crossing the threshold, making the chart memoryless post-alarm. This improves sensitivity for detecting subsequent shifts but loses information about the magnitude of the current shift. When false (default), the accumulator remains elevated after an alarm; all subsequent observations will also alarm until the process returns to the in-control state and the accumulator decays back below h.

Trait Implementations

impl Clone for CusumConfig

fn clone(&self) -> CusumConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CusumConfig

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

Formats the value using the given formatter.

impl Default for CusumConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CusumConfig

fn eq(&self, other: &CusumConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
