R: Information about the implemented covariance models

PrintModelList {RandomFields}

R Documentation

Information about the implemented covariance models

Description

PrintModelList prints the list of currently implemented models including the corresponding simulation methods

GetModelList returns a matrix of currently implemented models and their simulation methods

GetModelNames returns a list of currently implemented models

Usage


PrintModelList(operators=FALSE, internal=FALSE)

GetModelList(abbr=TRUE, internal=FALSE)

GetModelNames(stationary = c("any", "stationary", "variogram", "irf",
                             "auxmatrix", "auxvector", "gencovariance",
                             "nonstationary", "genvariogram", "prev.model"),
              isotropy = c("any", "isotropic", "spaceisotropic",
                           "zerospaceiso", "anisotropic", "prev.model"),
              multivariate = -9999:9999,
              operator, normalmix, finiterange, methods, internal=FALSE,
              dim = 1)

Arguments

`operators`	logical. Flag whether operators should be also considered.
`internal`	logical. Flag whether internal models should be also considered. In case of `PrintModelList` and `internal=2`, variants of internal models are also printed.
`abbr`	logical or numerical. If `TRUE` the names for the methods are abbreviated. If numerical, `abbr` gives the number of letters.
`stationary`	Selection criterion for the models
`isotropy`	Selection criterion for the models
`multivariate`	the dimension of the multivariate model
`operator`	logical. If missing any covariance model is returned; otherwise, the (non)primitive models are returned if `FALSE` (`TRUE`); see `Covariance` for details.
`normalmix`	logical. If missing any covariance model is returned; otherwise all normal scale mixture models are returned if `TRUE`
`finiterange`	logical. If missing any covariance model is returned; otherwise all models with finite range are returned if `TRUE`; note that some option are excluding, e.g. no normal scale model can have a finite range.
`methods`	If missing any covariance model is returned; otherwise the models with respective attribute are returned; see `PrintMethodList` for a complete list of methods
`dim`	dimension in which the model should be valid; there are some models where the validity in a given dimension depends on the some parameter; those models are returned partially only.

Details

See CovarianceFct and sophisticated models for a description of the models and their use

Value

PrintModelList prints a table of the currently implemented covariance functions and the matching methods. PrintModelList returns NULL.

GetModelNames returns a list of implemented models
