Topology of foreign exchange markets using hierarchical structure methods

Naylor, Michael J.; Rose, Lawrence C.; Moyle, Brendan J. - In: Physica A: Statistical Mechanics and its Applications 382 (2007) 1, pp. 199-208

This paper uses two physics derived hierarchical techniques, a minimal spanning tree and an ultrametric hierarchical … tree, to extract a topological influence map for major currencies from the ultrametric distance matrix for 1995–2001. We …

A nonspatial methodology for the analysis of two-way proximity data incorporating the distance-density hypothesis

DeSarbo, Wayne S.; Manrai, Ajay K.; Burke, Raymond R. - 1990

This paper presents a nonspatial operationalization of the Krumhansl (1978, 1982) distancedensity model of similarity. This model assumes that the similarity between two objects i and j is a function of both the interpoint distance between i and j and the density of other stimulus points in the...
