Table 1: Summaries of epistasis models for binding (A) and
folding (B). The leftmost column (column one) contains features. Any
categorical abstractions are listed directly below the category with
right justification. Column two gives the specific number of mutation
pairs for a given category, where applicable. For complex type
specifically, the number of complexes of that type are indicated in
parentheses. Column three is the change in R2(ΔR2), i.e., how much poorer the model fits the data
after removing this feature. In the case of the full model, column three
is the R2. Removal of a feature also removes all
subcategories and any interaction terms involving the feature. Column
four lists coefficients for the feature/interaction term in the full
model. The rightmost column contains p-values for the features, and
features within a given category.
