condCovariate: Conditioning of a Covariate

In spcopula: Copula Driven Analysis - Multivariate, Spatial, Spatio-Temporal

Description

Conditions the covariate on the central location in a stCoVarVineCopula.

Usage

condCovariate(stNeigh, coVarCop)

Arguments

stNeigh	a spatio-temporal neighbourhood stNeighbourhood with a covariate.
coVarCop	a function taking spatial and temporal indices and returning a copula object describing the dependence between variable of interest and covariate at this location in space and time.

Value

A vector of conditioned data, i.e. covariate|variable of interest
