Arm Parameter Values and Sensitivities.

Synthetic model parameters and their associated mean (nominal) values and standard deviations (SD) used to determine the sensitivity indices of Saltelli et al. [11]. Also shown are the resulting sensitivity indices. Sensitivity indices less than one-thousandth were reported as zero. Total variance was 1.56mm2, showing very small average deviations when using this approach. First-order sensitivity, S, can be interpreted as fraction of variance removable by perfectly correcting a factor. Total sensitivity, ST, can be interpreted as the fraction left after correcting all other factors. Most parameter values come from the literature, but instrument-specific parameters were determined empirically through repeated measurements (RM). Where parameter values were unavailable, 15% of the mean was used as a conservative estimate.Arm Parameter Values and Sensitivities.
