Implementations§

Source§

impl VariogramModel

Source

pub fn new( nugget: Real, sill: Real, range: Real, model_type: VariogramType, ) -> Result<Self, KrigingError>

Constructs a variogram model with validated parameters: nugget >= 0, sill > nugget, range > 0, all finite.

Source

pub fn new_with_shape( nugget: Real, sill: Real, range: Real, model_type: VariogramType, shape: Real, ) -> Result<Self, KrigingError>

Constructs a variogram model with an explicit shape parameter for Stable (alpha) or Matérn (nu). For other model types, shape is ignored. Stable: alpha in (0, 2]. Matérn: nu > 0.

Source

pub fn variogram_type(&self) -> VariogramType

Source

pub fn params(&self) -> (Real, Real, Real)

Source

pub fn shape(&self) -> Option<Real>

Shape parameter for Stable (alpha) or Matérn (nu). Returns None for 3-parameter models.

Source

pub fn semivariance(&self, distance: Real) -> Real

Semivariance at distance. Assumes distance >= 0 (e.g. from haversine); clamps negative input to 0.

Source

pub fn covariance(&self, distance: Real) -> Real
