Independent Predictors
	q Based on the previous analysis, we wish to use predictors that are independent of each other      è r12 = 0      è minimum useful correlation = 0. q The worst predictors are r12 = 1.0 q The desire for independent predictors is part of the motivation for Empirical Orthogonal Function (EOF) analysis. q EOF attempts to find a relatively small number of independent quantities which convey as much of the original information as possible without redundancy.
