The passage around this formula

…corpus. Two further quantities complete the construction. The mutation rate $\mu_c$=$\frac{1}{|\mathcal{M}_c^+|}$$\sum_{m\in\mathcal{M}_c^+}$$\mathbb{1}$[d($r_m$,$\rho$)>$\delta$] measures, among the trait-positive models in class c (the set $\mathcal{M}_c^+$ ), what fraction produce a response diverging from the seeded canonical form $\rho$ by more than a fixed threshold $\delta$ under a declared distance function d : a high $\mu_c$ says the trait is drifting as it moves, not being copied verbatim. The selection coefficient…
