  In this review of spatial statistics, expression (2) formalizes the general definition of a spatial statistical model given in Cressie (1993, Section 1.1). The model (2) covers the three principal spatial statistical areas according to three different assumptions about [D], which leads to three different types of spatial stochastic process, [Y ...

  Broad Idea I Compute Dist (N M) where Dist[i,j] is the euclidean distance between ith test example and jth training example. I Compute DistSorted by sorting the elements in each row of Dist and assigning to each row, the indices (into X train) of the sorted elements. I Compute KClosest by grabbing only the rst K columns of DistSorted. I Compute KClosestLabels by getting the output labels
