model.extend {RGeostats}

R Documentation

Convert a monovariate model into a multivariate one

Description

Convert a monovariate model into a multivariate one

Usage

model.extend(model, nvar, vars = NA, corr = NA)

Arguments

model	The model-class Class containing the monovariate model to be converted
nvar	New number of variables
vars	Vector giving the theoretical variances of the variables. The dimension should be 'nvar'. If not provided, the varainces are considered as all equal to 1.
corr	Theoretical Correlation matrix for the variables. The dimension should be 'nvar * nvar'.

Details

The new model is obtained as a Intrinsic extension of the initial one: all the simpe and cross structures are proportional to the initial structure. Their sills are dictated by the vector of variances and the matrix of correlations.

Value

The expanded model-class structure
