TcT_c

Symbol T_c

TcT_c is part of the quantity the equation computes from the expression on the right.

Understand this part →

Iˉc\bar I_c

Symbol bar I_c

bar IcI_c occurs above the fraction bar. The numerator is divided by the entire denominator below it.

I0I_0

Symbol I_0

the article’s single most important number, because it is the rate at which the trait shows up in models that never touched the source at all — the convergence baseline , the rate any theory of pure coincidence has to beat.

What the article says around this equation

Define the channel-attributable transfer rate for exposure class c∈\in\{V,H\} as TcT_c=Iˉc−I01−I0\frac{\bar I_c-I_0}{1-I_0} . This is a direct borrowing from the attributable-risk fraction used in outbreak epidemiology, where it measures what share of disease in an exposed group would disappear if the exposure were removed; here it measures what share of a model’s trait incidence would disappear if its exposure to the source artifact were removed, holding everything else about the model constant. TcT_c=0 means the exposed class shows the trait no more often than baseline: no signal. TcT_c=1 means every trait-negative case in the exposed class would have been positive under full exposure: the strongest…

Define the channel-attributable transfer rate for exposure class c∈\in\{V,H\} as TcT_c=Iˉc−I01−I0\frac{\bar I_c-I_0}{1-I_0} .

TcT_c=0 means the exposed class shows the trait no more often than baseline: no signal. TcT_c=1 means every trait-negative case in the exposed class would have been positive under full exposure: the strongest possible signal. TcT_c is dimensionless and bounded in [-1,1] ; a negative value, exposure suppressing the trait relative to baseline, is possible and would itself need explaining.
