Results of micro–macro multi-level models predicting three component measures of fight metrics from acoustic measures.
| Predictors | Factors | ||
|---|---|---|---|
| Fighting Experience | Fighting Success | Size | |
| Intercept | − 0.01 (.903) | 0.01 (.976) | − 0.01 (.966) |
| fo | − 0.10 (.059) | 0.04 (.405) | − 0.13 (.018) |
| fo-SD | − 0.04 (.507) | − 0.04 (.633) | 0.04 (.534) |
| Pf | − 0.20 (.002) | 0.02 (.832) | − 0.32 (< .001) |
| R2 | 0.04 | 0.01 | 0.08 |
Results are reported as effect size (p-value). Effect sizes are beta-weights, except for retirment status, which is odds ratio. In all models, the variance inflation factor (VIF) of each predictor was < 1.5. fo = fundamental frequency; fo-SD = Variability in fundamental frequency; Pf = formant position.
