Automatic PluriGaussian Sill Fitting

Description

Fit the Sills of the Underlying GRF Models in the PluriGaussian scope

Usage

model.pgs.fit(vario, rule = rule.input(), model1 = NA, model2 = NA, dbin = NA, dbout = NA, props = NA, flag.stat = TRUE, niter = 100, wmode = 2, draw = TRUE, flag.ask = TRUE, ...)

Arguments

vario

The vario-class Class containing the experimental variogram of the indicators of the different facies

rule

The rule-class Class containing the Lithotype Rule.

model1

The model-class Class containing the Model to be fitted for the first underlying GRF.

model2

The model-class Class containing the Model to be fitted for the second underlying GRF.

dbin

The db-class Class containing the input data

dbout

The db-class Class containing the output target points

props

Vector giving the constant facies proportions in the stationary case.

flag.stat

When TRUE, the proportions are stationary and read from the array props. Otherwise, the proportions are read from the proportion variables of the output db-class file.

niter

Maximum number of iterations in the fitting procedure.

wmode

Type of the weighting function used in the fitting procedure. This function is defined in the case of several directional experimental variograms, calculated in a multivariate case:

  • 0: The weight is constant

  • 1: The weight is proportional to the number of pairs

  • 2: The weight is proportional to the number of pairs and inverse proportional to the distance

  • 3: The weight is inverse proportional to the number of lags for each direction

draw

When TRUE, both the experimental variograms and the Model (interpreted through the variogram of indicators) are represented graphically. Otherwise, no graphic is produced.

flag.ask

When TRUE, the parameters of the model are entered interactively. When FALSE and if a model is provided as an argument, the automatic sill takes place and no question is asked.
