Spatial Correlation Structure Classes

Description

Standard classes of spatial correlation structures available for the georamps function.

Spatial Structures:

corRCauchy
Cauchy correlation.
corRExp
exponential correlation.
corRExpwr
powered exponential correlation.
corRGaus
Gaussian correlation.
corRGneit
Gneiting approximation to Gaussian correlation.
corRLin
linear correlation.
corRMatern
Matern correlation.
corRSpher
spherical correlation.
corRWave
sine wave correlation.

Spatio-Temporal Structures:

corRExp2
exponential correlation.
corRExpwr2
powered exponential correlation.

Temporally Integrated Spatial Structure:

corRExpwr2Dt
powered exponential correlation.

Note

Users may define their own corStruct classes by specifying a constructor function and, at a minimum, methods for the functions corMatrix and coef.
