model.extend {RGeostats} | R Documentation |
Convert a monovariate model into a multivariate one
model.extend(model, nvar, vars = NA, corr = NA)
model |
The |
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'. |
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.
