corRExpwr2
(Package: ramps) :
Non-Separable Powered Exponential Spatio-Temporal Correlation Structure
This function is a constructor for the 'corRExpwr2' class, representing a non-separable spatial correlation structure. Letting rs denote the spatial range, ps the spatial shape, rt the temporal range, pt the temporal shape, and lambda the space-time interaction, the correlation between two observations a distance d apart in space and t in time is exp(-(d/rs)^ps - (t/rt)^pt - lambda * (d/rs)^ps * (t/rt)^pt).

corRGneit
(Package: ramps) :
Gneiting Spatial Correlation Structure
This function is a constructor for the 'corRGneit' class, representing the Gneiting approximation to the Gaussian correlation structure. Letting r denote the range, the correlation between two observations a distance d < r / s apart is (1 + 8 * s * x + 25 * (s * x)^2 + 32 * (s * x)^3) * (1 - s * x)^8, where s = 0.301187465825. If d >= r / s the correlation is zero.
