Abstract :
In this paper, we define a spatial skew and heavy-tailed random field by an extended
version of multivariate generalized skew Laplace distribution. The Bayesian spatial
regression model is developed to explain the spatial data. A simulation study is then
carried out to validate and evaluate the performance of the proposed model. The
application of this model is also demonstrated in an analysis of a geological real data
set.
