Interest rates hierarchical structure

Di Matteo, Tiziana; Aste, Tomaso; Hyde, Stephen; Ramsden, Stuart


We propose a general method to study the hierarchical organization of financial data by embedding the structure of their correlations in metric graphs in multi-dimensional spaces. An application to two different sets of interest rates is discussed by constructing triangular embeddings on the sphere. Three-dimensional representations of these embeddings with the correct metric geometry are constructed and visualized. The resulting graphs contain the minimum spanning tree as a sub-graph and they...[Show more]
