Query: Nearest-Neighbor Geostatistical Models for Non-Gaussian Data   We develop a class of nearest-neighbor geostatistical models for non-Gaussian
data that provides flexibility and scalability. The model is defined on a
directed acyclic graph through a weighted combination of first-order spatially
varying conditional densities, for each one of a given number of neighbors. It
is then extended to a proper spatial process, referred to as the
nearest-neighbor mixture transition distribution process (NNMP). We provide
conditions to construct general NNMP models with pre-specified stationary
marginal distributions. We also establish lower bounds for the resulting
strength of the tail dependence, demonstrating the flexibility of NNMPs to
quantify multivariate dependence using a bivariate distribution specification.
We formulate a Bayesian hierarchical model, focusing on spatially dependent
weights, that is locally adaptive, and provides accurate predictions. NNMPs lay
out a new computational approach to handling spatial data sets, leveraging a
mixture model structure to avoid computational issues that arise from large
matrix operations. We illustrate the benefits of the NNMP framework using
synthetic data examples as well as analyzing sea surface temperature
observations from the Mediterranean Sea.
