Struct PatchCovariances 

pub struct PatchCovariances {
    pub covariance: Array2<Option<FlatMatrix>>,
    pub sensitivity: Array2<Option<FlatMatrix>>,
    /* private fields */
}

Each patch’s covariance of a map’s CountsMap::quantities, their change with the shared quantities, and the shared quantities’ covariance that joins the patches.

Fields

covariance: Array2<Option<FlatMatrix>>

Each patch’s covariance of CountsMap::quantities, the shared quantities’ uncertainty included; the row and column of one held on a bound, or not determined by the counts, alone or through a shared quantity, are NaN. None where the patch has no fit or the map has no shared covariance.

sensitivity: Array2<Option<FlatMatrix>>

Each patch’s change of CountsMap::quantities per unit change of each of CountsMap::shared at fixed counts, −F_oo⁻¹ F_os of its information; the row of a quantity held on a bound or not determined by the counts is NaN. None where the patch has no fit.

Implementations

impl PatchCovariances

pub fn cross_covariance( &self, a: (usize, usize), b: (usize, usize), ) -> Option<FlatMatrix>

The covariance of patch a’s CountsMap::quantities with a different patch b’s, which only the shared quantities carry, G_a C_ss G_bᵀ over those not held on a bound; for a = b, the part of Self::covariance they carry. None where either patch is outside the grid or has no Self::sensitivity, or the map has no CountsMap::shared_covariance.
