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