All birds: model selection statistics for the confidence set of models (relative likelihood >0.05) and the global model for testosterone-treated male and female house sparrows
| Rank | Model i | K | AICc | Δi | wi |
|---|---|---|---|---|---|
| 1 | Treatment + sex + frailty(family) | 3 | 479.38 | 0.00 | 0.55 |
| 2 | Frailty(family) | 1 | 480.77 | 1.39 | 0.28 |
| 3 | Treatment * sex + frailty(family) | 4 | 482.99 | 3.61 | 0.09 |
| 4a | Treatment + sex * year + frailty(family) | 5 | 484.24 | 4.86 | 0.05 |
Factors in the statistical model were treatment, sex, year of treatment, and family as a random factor. Model notation: “+” denotes additive effect; “*” denotes interaction. For each model, the following parameters are given: the number of estimable parameters (K), Akaike’s information criterion for small samples (AICc), the difference between the minimum AICc of the top model and the model considered (Δi), and Akaike’s weights (wi)
