Consider a finite set of spatial locations and a model whose covariance structure is given by a parsimonious Matérn covariance structure. Finite-location identifiability conjecture…

Let $X$ and $W$ be spatial Gaussian random fields on ${ R} ^d$ with smoothness parameters $\nu_X$, $\nu_W$, and cross-smoothness parameter $\nu_{XW}$. Assume that $\nu_X$ is not a…
