Value

  • Available standard classes:
  • corAR1autoregressive process of order 1.
  • corARMAautoregressive moving average process, with arbitrary orders for the autoregressive and moving average components.
  • corCAR1continuous autoregressive process (AR(1) process for a continuous time covariate).
  • corCompSymmcompound symmetry structure corresponding to a constant correlation.
  • corExpexponential spatial correlation.
  • corGausGaussian spatial correlation.
  • corLinlinear spatial correlation.
  • corRatioRational quadratics spatial correlation.
  • corSpherspherical spatial correlation.
  • corSymmgeneral correlation matrix, with no additional structure.

Note

Users may define their own corStruct classes by specifying a constructor function and, at a minimum, methods for the functions corMatrix and coef. For examples of these functions, see the methods for classes corSymm and corAR1.
