Iavg 1.70 1.68 1.70
Imin 1.59 1.61 1.63
  1. Coefficients given for reference sample design Dataset 5. Values greater than 1 indicate higher Z-statistics with the pairwise technique. Data is shown for both pooling metrics Iavg and Imin and for three different image processing techniques. Every linear regression analysis produced an R2 value greater than 0.89 (data not shown).
