Non-separable spatiotemporal covariance function on spherical distances

Description

Compute pairwise covariances between two sets of locations using a non-separable spatiotemporal model with Great circle distances from Porcu et al. (2016), eq. (15).

Usage

stmra_cov_porcu_etal_15(locs1, locs2, theta)

Arguments

locs1	matrix with rows representing points and columns representing coordinates
locs2	matrix with rows representing points and columns representing coordinates
theta	vector of parameters (see Details)

Details

Parameter vector theta includes partial sill, spatial scale, temporal scale, nugget (in this order).
