Vignettes using the cross variogram
Source:vignettes/crossvariogram_landing.Rmd
crossvariogram_landing.RmdThe cross variogram is used in cokriging, which uses multiple variables in the spatial interpolation model. The cross variogram is defined as
\[ \gamma(t) = \frac 1 2 \mathrm{Cov}(X_t - X_0, Y_t - Y_0), \]
where \(Y\) is another variable. The
cross variogram also has nugget, sill, and range. It shows how the
covariance between two variables changes with distance.
Voyager supports multiple bivariate spatial methods, and
the cross variogram is one of them.
Below is a list of vignettes that use the cross variogram. The links point to the sections that use the cross variogram. The corresponding Google Colab notebooks are also linked to. The list is sorted by technology.
