  1. λ was modeled as a linear function of 3 factors: group (black, red, green), environment (uninfected, infected, stressed), and genotype (unselected control, refractory, highly susceptible), and their interaction terms. For each of the 18 models, the model structure shows the factors and interaction terms included in the model. Each model was assigned a unique identification number (id). Also shown for each model are the number of parameters (param), residual standard error (res s.e.), the adjusted r2 value (r2), the F-statistic of the model (F), the p-value of the model (p), and Akaike's Information Criterion (AIC). For each model, the residual degrees of freedom are 26 minus the number of parameters. In the model structure column, group, environment, and genotype are abbreviated as D, E, and G, respectively.
