Abstract:
 
We describe four methods for factor analysis of spatially
correlated vectors: the Linear Model of Coregionalization and
three recently proposed alternatives. We apply the three methods
to analyze the concentrations of nine chemicals in water samples
taken from 306 springs. The methods give quite different
results, with those of the Linear Model of Coregionalization
being much more interpretable. We suggest some possible
explanations for this, which may be relevant in other
applications as well.
 
Joint with Bella Vakulenko-Lagun and Michael Zilberbrand.
