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 corRStruct classes by specifying a constructor function and, at a minimum, methods for the functions corMatrix and coef.
