Summary of statistical modeling outputs for aphid parasitism assays. For each performance parameter, the treatment factor, model basis, error distribution, analysis method, and statistical outputs are shown. Type II Wald χ 2 analysis of deviance and observation of fitted‐residual plots was conducted throughout the modeling simplification process to ensure data fitted the model parameters and that model simplification was justified
| Response variable | Treatmentfactor | Model basis | Error distribution | Modelanalysis | Test statistic | Degrees of freedom (residuals) | P value |
|---|---|---|---|---|---|---|---|
| Susceptibility to parasitism (number of aphid mummies) | Endosymbiont infection | Generalized linear mixed effects model | Binomial | Type II Wald χ 2 analysis of deviance (χ 2 Test) | χ 2 = 92.07 | 1 (24) | <0.001 |
| Sex of wasp progeny | Endosymbiont infection | Generalized linear mixed effects model | Binomial | χ 2 = 0.07 | 1 (100) | 0.787 |
