The error calculated from leave-one-out cross-validation during
the baseline interpolations ranged from 0.51 to 41.9 mg m3 with a
mean error of 7.0 mg m3
. The minimum cost was 91,087 to a
maximum cost of 1,733,835; the cost had a range of 1,642,748. The
index values varied from 0.052 to 1.000 and are presented in
Table 2. The index values calculated during the multiplication factor
sensitivity analysis are included in Table 2.
