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
.
