Table 1. Hypotheses.
| Hypothesis | Question | Variables |
|---|---|---|
| H0 | Null model | Y = control variables |
| H1 | Does health differ by age or sex class? | Y = sex + age |
| H2 | Does rank influence health beyond effects of age and sex? | Y = sex + age + rank |
| H3 | Does dominance certainty influence health beyond effects of age and sex? | Y = sex + age + DC |
| H4 | What are the relative impacts of rank and dominance certainty on health? | Y = sex + age + rank + DC |
| H5 | Does the impact of rank on health depend upon dominance certainty? | Y = sex + age + rank + DC + rank*DC |
| H6 | Does the impact of rank differ for juveniles, adults and geriatric animals? | Y = sex + age + rank + rank*age |
| H7a | Does the impact of status (i.e. rank) differ for males and females? | Y = sex + age + rank + rank*sex |
| H7b | Does the impact of status (i.e. dominance certainty) differ for males and females? | Y = sex + age + rank + DC*sex |
| H8 | Due to sex differences in how status is attained, does the interaction of rank and DC affect males and females differently? | Y= sex + age + rank + DC + sex*rank + sex*DC + rank*DC + sex*DC*rank |
Notes:
All models include a random effect of cage.
DC, dominance certainty.
