- •
Considering first and second order of variables the FCM was optimized after 15 steps.
- •
An ORCM with R2 (pred) = 78% in area indicates average C.I. = 93% for elements.
- •
Modeling accompanying the interaction effects is efficient for demonstrate heterogeneity.
- •
By increasing Hg concentration from vein to background, Au-Ag line shifted downward.
