Distribution of facial integration magnitudes as measured by the between-block correlation coefficient of PLS2.

Legend: SV: singular value, r: between-block correlation coefficient, %Cov.: percentage of squared between-block covariance explained by this axis.图例：SV：奇异值（singular value）；r：块间相关系数（between-block correlation coefficient）；%Cov.：该轴所解释的块间协方差平方百分比。
