dbmap |
The |
struct |
List of basic structures to be used |
constraints |
Value giving the constraints on the sills of the model. It must be positive. Otherwise, no constraints is applied on the Sill estimation. In the multi-variate case, the same value applies to each variable. This is incompatible with the 'flag.norm.sill' flag. |
auth.aniso |
When TRUE, the anisotropy will be checked |
auth.rotation |
When TRUE, the fit will look for rotation in anisotropy |
auth.locksame |
When TRUE and if an anisotropy is allowed (auth.aniso), all the basic structures should share the same rotation. |
auth.lock2d |
When TRUE, the anisotropy rotation will only consider a rotation around the Z-axis. The Dip and Plunge angles are kept equal to zero. |
flag.goulard |
When TRUE, the Goulard algorithm is used for the determination of the Sills (quicker). Otherwise Sills are infered using the standard Foxleg algorithm. |
flag.noreduce |
When TRUE, the useless basic structures must not be discarded. |
flag.norm.sill |
When TRUE, the automatic fit must fulfill the constraint that the sum of the sills must always be equal to 1 |
flag.keep.intstr |
When TRUE, the fitting procedure must always maintain at least one intrinsic basic structure. If no intrinsic basic structure is provided in the initial template, the automatic fitting procedure fails. |
flag.intrinsic |
In the case of an Automatic Model Fitting in the multivariate case, when TRUE, the resulting Model is Intrinsic (all simple and cross-variograms are proportional) |
param |
List of initial values for the parameters to be fitted
For details see |
lower |
List of lower bounds for the parameters to be fitted
For details see |
upper |
List of upper bounds for the parameters to be fitted
For details see |
equal |
List of equalities for the parameters to be fitted
For details see |
draw |
When TRUE, both the experimental variograms and the Model are represented graphically. Otherwise, no graphic is produced. |
maxiter |
Maximum number of iterations |
verbose |
Verbose option
|
tolstop |
Tolerance for the distance between the experiment and the model. This quantity is transformed internally proportionally to the variance of the data. |
epsdelta |
Tolerance for the direction increment used in the gradient search |
tolsigma |
Percentage of the variance below which a basic structure will be discarded |
delta |
Delta value |
