matern.hessian.phi

Computes the second derivative of the Matern correlation function with respect to \(\phi\).

Geostatistical analysis of continuous and count data.
Implements stationary Gaussian processes with Matérn correlation for spatial prediction,
as described in Diggle and Giorgi (2019, ISBN: 978-1-138-06102-7).
