uc |
The drift description. Use command |
polygon |
The |
mean |
Array containing the mean of each variable, used in the case of Simple (Co-)Kriging |
dbout |
The |
calcul |
Option for the calculation of the global estimation. It can be:
|
ivar |
Rank of the target variable (starting from 1). Note that the transitive global estimation is not available in the multivariate case. |
verbose |
1 for a verbose output; 0 otherwise |
ndisc |
Number of discretization steps used for:
|
seed |
Seed used for the generation of random numbers. When 0, the seed is not initialized. |
flag.regular |
When TRUE, use the regular transitive method; otherwise use the stratified transitive method. |
flag.polin |
If TRUE, only the input data which belong to the Polygon are used for the estimation. Otherwise, all the data are used (even if they do not lie within the polygon). See also the comments on the argument 'combine'. |
flag.wgt |
When TRUE, a vector which contains the kriging weights is provided as a returned argument. This option is only available when calcul="krige". |
combine |
When a selection of active data is performed within a Polygon
('flag.polin' set to TRUE) and if a selection already exists, the
'combine' keyword indicates how the polygon selection must be
combined with the previous one.

A list containing the following information:
* zest : Global estimation
* sse : Standard deviation on the Global estimated Mean
* cv : CV
* wgt : a vector containing the kriging weights (of the whole data set, regardless of any selection) when calcul="krige", NA otherwise.
