Ordinary kriging (alias of Krig)

The same estimator as Krig and Krigsm; delegates rather than carrying a second copy of the solver.

Usage

KrigCl(
  known_coords,
  known_values,
  predict_coords,
  nugget = 0,
  sill = 1,
  range_ = 1
)

Arguments

known_coords

Matrix of observed locations, one row per point.

known_values

Observed values, one per row of known_coords.

predict_coords

Matrix of prediction locations.

nugget

Variogram nugget. Default 0.

sill

Variogram sill. Default 1.

range_

Variogram range. Default 1.

Value

As Krig.
