value of these 17 questions was 437.35 (p<0.001) and the total score was not used in the study.
(interactions evaluated as product terms and interpreted based on product term p-values: We tested all PCBs groups and HCB, p,p'-DDE, lead, and breastfeeding history because relatively few studies have examined the concurrent effects of the most common pollutants to which children may be exposed.
Overall, results support this hypothesis as revealed in nonadditivity
of the individual factors when ISR was present but not when it was absent (i.e., a three-way interaction was observed, Figure 4).
For example, in simulation studies, regardless of nonlinearity or nonadditivity
, random forest performed well in terms of covariate balance between treatment groups and may result in further reduction in bias of the effect estimate when compared to traditional logistic regression (Setoguchi et al.
Fuzzy measure is the generalization of classical measure by using nonadditivity
instead of additivity, which makes fuzzy measure be able to describe the importance of each individual information source (attribute or classifier) as well as the interaction , among them.

It is certainly understandable that the BEA would be concerned about nonadditivity
, although it accepted nonadditivity
in its real estimates when moving to chain weighting in the mid-1990s.
In addition, the influence of nonlinearities causes nonadditivity
of other physical effects.
A new way to estimate the contribution of a risk factor in populations avoided nonadditivity
. J Clin Epidemiol.
The potential energy should be adequately described by the sum of pair and three-body potentials; the relatively small size of the three-body contribution compared to the pair contribution suggests that nonadditivity
of the potential at the four-body level should be tiny (this could be checked by ab initio calculations at selected configurations).
