fraction

What this part means

Divide the expression above the line by the one below it.

Its job in the formula

The expression above the fraction bar is divided by the complete expression below it. The denominator must not be zero.

The passage around this formula

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…
