A numeric (\(d \times 2\))-matrix or (\(d \times 3\))-matrix
Coordinates on a sphere for a fixed radius radius
are passed in lon/lat format expressed in decimal degrees.
A numeric vector giving 1-dimension of
spatial coordinates; Optional argument, the default is NULL.
A numeric vector giving 1-dimension of
spatial coordinates; Optional argument, the default is NULL.
A numeric vector assigning 1-dimension of temporal coordinates.
A list of \(m\) numeric (\(d_t \times 2\))-matrices
containing dynamical (in time) spatial coordinates. Optional argument, the default is NULL
String; the name of a correlation model.
A numeric vector or a (\(n \times d\))-matrix or (\(d \times d \times n\))-matrix of observations.
String; the name of the spatial distance. The default is Eucl,
the euclidean distance. See the Section Details.
String; "fitting" to call the fitting procedure and "simulation" to call the simulation procedure.
A named list giving the values of the parameters that will be considered as known values.
Logical; if FALSE (the default) the data
are interpreted as a vector or a (\(n \times d\))-matrix,
instead if TRUE then (\(d \times d
\times n\))-matrix is considered.
String; the configuration of the composite likelihood.
Numeric; an optional positive value indicating the maximum spatial distance considered in the composite-likelihood computation.
Numeric; an optional positive integer indicating the order of neighborhood in the composite likelihood computation. See the Section Details for more information.
Numeric; an optional positive value indicating the maximum temporal lag considered in the composite-likelihood computation.
Numeric; the radius of the sphere in the case of lon-lat coordinates. The default is 6371, the radius of the earth.
String; the density associated to the likelihood
objects. Gaussian is the default.
Numeric; number of trials for binomial random fields.
A numeric vector of parameter values required in the simulation procedure of random fields.
A numeric vector of scaling factor to improve the
maximizing procedure, see optim.
A numeric vector of parameters ranges, see
optim.
A named list with the initial values of the parameters that are used by the numerical routines in maximization procedure.
String; the name of the type of covariance matrix.
It can be Standard (the default value) or
Tapering for taperd covariance matrix.
Numeric; an optional value indicating the separabe parameter in the space time adaptive taper (see Details).
String; the type of likelihood objects. Temporary value set to be "WLeastSquare" (weigthed least-square) in order to compute the starting values.
String; the real type of likelihood objects. See GeoFit.
Logical; if TRUE the likelihood objects are
weighted, see GeoFit.
The type of copula.
Numeric; Matrix of space-time covariates.
Logical; if TRUE then the distances in the composite likelihood
are computed before the optmization.
Logical; if TRUE two simmetric weights are not considered
