What this part means

m is an argument of the function-like quantity on the left; its role is set by that function’s stated inputs.

The passage around this formula

Sort a population of models M\mathcal{M}=\{m1m_1,…\dots,mNm_N\} into the three exposure classes just defined, MV\mathcal{M}_V , MH\mathcal{M}_H , and M∅\mathcal{M}_\varnothing . For each model m , define its trait incidence as I(m)=1k\frac{1}{k}∑q∈Q\sum_{q\in Q}1\mathbb{1}[rm(q)r_m(q)∈\inT\mathcal{T}] , where Q is the held-out probe set of size k and rm(q)r_m(q) is m ’s response to probe q . I(m) is a dimensionless rate between 0 and 1: the fraction of probes that elicit the trait. Average I(m) within each…
