Statistical methods on graphs
Abstract/Contents
- Abstract
- In relational data the most basic statistical questions focus on modeling the structure of the network and on making inferences about the nodes. These questions are addressed separately with a simple but novel model for each. On the side of graph structure, a class of "monotone random graphs" are examined where n vertices are totally ordered such that independent edge probabilities satisfy the partial ordering p_{i, j} ≤ p_{k, l} for i ≤ k and j ≤ l. The MLE of the graph's edge parameters can be solved by isotonic regression (equivalent to projection onto a convex cone), and this MLE is a consistent estimator. On the nodal inference side, the focus is specifically on multi-relational networks. This approach constructs a design matrix by multiplying a vector of nodal features with each adjacency matrix in which the nodes are embedded. After constructing this design matrix through nodal diffusion, standard statistical learning techniques can be applied to the design matrix.
