Spatial Correlation Structure Classes

Description

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

Spatial Structures:

corRExp
exponential correlation.
corRExpwr
powered exponential correlation.
corRGaus
Gaussian correlation.
corRLin
linear correlation.
corRMatern
Matern correlation.
corRRatio
rational quadratic 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.
