Parameter correlations.

This figure shows correlation matrices for parameter values derived from linear analysis (A), and bootstrapping (B), for Kr (green frame), kni (red frame), and gt (blue frame). Parameter notation: (production rate), (decay rate), (diffusion rate), and (production delay; see equation 1). Colors indicate sign and strength of correlations. Matrices in (A) are calculated from equation 6 (see Materials and Methods). Matrices in (B) are derived from the singular value decomposition of bootstrap distributions.

本图展示了针对Kr（绿框）、kni（红框）与gt（蓝框）的线性分析（A）与自助法（bootstrap）所得参数值的相关矩阵。参数定义如下：（生成速率）、（衰变速率）、（扩散速率）以及（生成延迟；详见公式1）。颜色用以表征相关系数的符号与强度。（A）中的矩阵由公式6计算得到（详见材料与方法）。（B）中的矩阵则由自助法分布的奇异值分解得到。
