model.covmat.inchol {RGeostats}R Documentation

Establish the Incomplete Cholsky Decomposition of the covariance matrix

Description

Establish the Incomplete Cholsky Decomposition of the covariance matrix

Usage

model.covmat.inchol(db, model = model.input(), eta = 0.05,
      npivot.max=0, ranks1=NA, flag.sort = TRUE, center=NA, verbose = FALSE)

Arguments

db

Name of the db-class which contains the first Db

model

Name of the model-class which contains the model

eta

Tolerance part of the variance which is not reproduced.

npivot.max

Maximum number of pivots (if positive).

ranks1

The array of sample ranks already selected as pivots (numbered starting from 1).

flag.sort

When TRUE, the output array G(nech,np) has the order of its lines ordered as the order of the initial samples. When FALSE, the pivots are listed in the first rows of G, followed by the standard samples (possibly shuffled).

center

When defined, this gives the coordinates of a centering sample used in order to establish the covariance matrix of increments.

verbose

Verbose flag

Details

The algorithm stops as soon as one of the following criteria is met:

Value

A list which contains:
