Locally epistatic models for genome-wide prediction and association by importance sampling

Table 4 A scenario which shows an interaction pattern between two markers generated by a simple rule “\(I(m1<2)*I(m2>1)\rightarrow\) – else +”

The standard multiplicative formulation (\(m1\times m2\)) cannot adequately represent this interaction and other terms would be needed in the model (additive, additive \(\times\) additive, additive \(\times\) dominance, dominance \(\times\) dominance, see factorial model in [59, 60])
