REDUCTION OF DIMENSIONALITY FOR HEURISTIC PURPOSES
Bernard R. Baum · Taxon · 1977
Summary Interpretation of numerical results in analysis of relationships between OTU's or between variables is profitably achieved when the Q or R matrix can be reduced in dimensionality. An approach is proposed, viz. transformation of the elements of the matrix such that the first few eigenvalues much increase relative to others while minimizing distortion of the matrix, for the cases when eigenvalues computed from such a matrix gradually decrease. A numerical example is given using the transformation Yij = Xijn
