RandomFields (version 3.1.16)

Constants: Constants used in RandomFields (RC constants)

Description

Several constants are provided that might make the use of some functions easier, e.g. RFgetModelNames

Value

RC_TYPENAMES = c("tail correlation function", "positive definite", "variogram", "negative definite", "process", "method for Gauss process", "method for Brown-Resnick process", "shifted shape function", "distribution family", "shape function", "trend", "interface", "undefined", "other type")RC_DOMAIN_NAMES = c("single variable", "kernel", "framework dependent", "mismatch") RC_ISONAMES = c("isotropic", "space-isotropic", "zero-space-isotropic", "vector-isotropic", "symmetric", "cartesian system", "earth system", "spherical system", "cylinder system", "non-dimension-reducing", "parameter dependent", "") RC_MONOTONE_NAMES = c("mismatch in monotonicity", "submodel dependent monotonicity", "previous model dependent monotonicity", "parameter dependent monotonicity", "not monotone", "monotone", "Gneiting-Schaback class", "normal mixture", "completely monotone", "Bernstein") RC_ISOTROPIC gives the numerical code for option "isotropic"RC_SPACEISOTROPIC gives the numerical code for option "space-isotropic"RC_CARTESIAN_COORD gives the numerical code for option "cartesian system"RC_GNOMONIC_PROJ gives the numerical code for the gnomonic projection, see also zenit in RFoptions.RC_ORTHOGRAPHIC_PROJ gives the numerical code for the orthographic projection, see also zenit in RFoptions.RC_EARTH_COORDS gives the numerical code for option "earth coordinates"RC_SPHERICAL_COORDS gives the numerical code for option "earth coordinates"RC_OPTIMISER_NAMES and RC_NLOPTR_NAMES give the names for the options optimiser and algorithm, respectively, RFfitoptimiser.RC_LIKELIHOOD_NAMES = c("auto", "full", "composite", "tesselation") gives the names of the ML variants: (i) internal choice according to the number of data, (ii) full likelihood, (iii) (pairwise) composite likelihood, and (iv) composite likelihood based on a tesselation of the space.
