Struct PcaObservation 

pub struct PcaObservation {
    pub run_index: usize,
    pub t2: Option<f64>,
    pub q_stat: Option<f64>,
    pub n_components: usize,
    pub pc1_loading: Option<Vec<f64>>,
    pub residual_vector: Option<Vec<f64>>,
    pub sensor_labels: Vec<String>,
}

A single multivariate process observation expressed in terms of the PCA residual statistics already computed by the upstream FDC system.

All fields are received from the FDC system; the DSFB observer never writes back to it.

Fields

run_index: usize

Zero-indexed run / lot identifier.

t2: Option<f64>

Hotelling’s T² statistic for this run (Mahalanobis distance² in the PC subspace).

q_stat: Option<f64>

Q-Statistic (Squared Prediction Error / SPE) for this run.

n_components: usize

Number of principal components retained by the upstream FDC model.

pc1_loading: Option<Vec<f64>>

Loadings of the first principal component, one entry per sensor. Must have length == number of sensors selected for PCA. None when the FDC model does not expose loadings.

residual_vector: Option<Vec<f64>>

Raw normalised residual vector (one entry per sensor). None when the FDC system does not expose individual residuals.

sensor_labels: Vec<String>

Sensor labels corresponding to entries in pc1_loading and residual_vector.

Trait Implementations

impl Clone for PcaObservation

fn clone(&self) -> PcaObservation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PcaObservation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PcaObservation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PcaObservation

fn eq(&self, other: &PcaObservation) -> 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.

impl Serialize for PcaObservation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
