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, default is NULL.
A numeric vector giving 1-dimension of spatial coordinates; optional argument, 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, default is NULL.
String; the name of a correlation model.
A numeric vector or a (\(n \times d\))-matrix or (\(d \times d \times n\))-array of observations.
String; the name of the spatial distance. Default is "Eucl" (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 (default) the data are interpreted as a vector or a (\(n \times d\))-matrix;
if TRUE then a (\(d \times d \times n\))-array 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.
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 factors to improve the maximizing procedure; see optim.
A numeric vector of parameter ranges; see optim.
Numeric; the radius of the sphere in the case of lon-lat coordinates.
The default is 6371, the radius of the earth.
A named list with the initial values of the parameters that are used by the numerical routines in the maximization procedure.
String; the name of the type of covariance matrix. It can be "Standard" (default) or "Tapering" for tapered covariance matrices.
Numeric; an optional value indicating the separability parameter in the space-time adaptive taper (see Details).
String; the type of likelihood objects. Temporary value set to "WLeastSquare" (weighted least-square) in order to compute starting values.
String; the real type of likelihood objects. See GeoFit.
Logical; if TRUE the likelihood objects are weighted; see GeoFit.
String; the type of copula.
Numeric; matrix of space-time covariates.
Logical; if TRUE then the distances in the composite likelihood are computed before the optimization.
Logical; if TRUE symmetric weights are not considered.
Numeric; a value in \((0,1]\) specifying the expected fraction of nearest-neighbor pairs retained through stochastic thinning.
If 1 (default), no thinning is applied and all nearest-neighbor pairs are used. If <1, pairs are randomly retained using independent Bernoulli sampling.
String; thinning scheme used when p_neighb<1. Default is "iid" (independent Bernoulli thinning).
