Bayesian nonparametric methods has grown extensively during the past years in analyzing spatially related data. Random Bernstein polynomial prior have been studied and applied in several areas including spatial statistics. In this paper, we will extend the multi-dimensional Bernstein prior to a more general multi-dimensional Feller prior and prove some theoretical property.
