Table 5. Pearson product  moment correlation coefficients between the unpredictability (H), diversity (S) and efficiency ratio (E) of the boxing punching action patterns. A nonlinear regression (stretched exponential) fit between the entropy (unpredictability) and symmetry (diversity) measures with the efficiency ratio (E) reveals much higher relationships.
