Spatial Correlation Structure Classes

Spatial Correlation Structure Classes

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.
