Equation (13.15) gives L(Ci|Cj) = 1 – ij, where ij is the Kronecker delta. Substituting in
equation (13.13) simplifies the summation hugely, as all but one of the terms is zero,
leaving the result:
13.2
In the cross-over region (cf. Fig. 13.3b), the overlap region represents errors. Near the
very centre of this region, where we might instigate rejection rather than incur a high error
rate, the incidence of errors is approximately equal to the incidence of correct decisions.
