Multivariate receptor modeling by N-dimensional edge detection
The mathematical details of the Unmix multivariate receptor model for air quality data are given. Primary among these is an algorithm to find edges (more correctly hyperplanes) in sets of points in N-dimensional space. An example with simulated data is given. (C) 2002 Elsevier Science B.V.
