Struct TruingPlanInformationV1

    pub sensitivity_ratio: f64,

    pub minimum_singular_value: f64,
    pub maximum_singular_value: f64,

}

Information diagnostics for the selected design.

Fields

sensitivity_ratio: f64

||BC*d(drop)/d(BC)|| / ||MV*d(drop)/d(MV)||, after weighting by the declared observation sigma.

condition_number: Option<f64>

Condition number of the independently column-normalized MV/BC normal matrix. None means one column is zero or the design is rank deficient.

minimum_singular_value: f64

Smallest singular value of the observation-sigma-weighted fractional Jacobian. Its unit is inverse observation sigma (dimensionless here).

maximum_singular_value: f64

weak_axis_fractional_sigma_1sd: Option<f64>

Local 1-sigma uncertainty along the weakest MV/BC fractional-parameter direction (1 / minimum_singular_value). It scales linearly with the declared measurement sigma. None denotes a rank-deficient design.

log_determinant: Option<f64>

Natural log of the unregularized 2x2 information determinant. None denotes a rank-deficient design.

expected_information_gain_nats: f64

0.5 * log det(I + F), a finite local-Gaussian information summary in nats. I is an identity reference information matrix in fractional MV/BC coordinates (equivalently, unit reference covariance for those fractional perturbations), not a hidden truing prior.

Trait Implementations

impl Clone for TruingPlanInformationV1

fn clone(&self) -> TruingPlanInformationV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TruingPlanInformationV1

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

Formats the value using the given formatter.

impl PartialEq for TruingPlanInformationV1

fn eq(&self, other: &TruingPlanInformationV1) -> 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 TruingPlanInformationV1

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
