Table 2.
Significant explanatory variables from the final Zero-truncated Negative Binomial regression (ZTNB) model that estimated the volume of traded livestock movements between location (village/town) pairs.
Variable | Estimate (95% CI) | Ratio (95% CI) | p value |
---|---|---|---|
Pairwise distance between origin and destination | −0.95 (− 1.13 to 0.77) | 0.39 (0.32–0.46) | < 10^ − 9 |
Livestock population size at destination | 0.24 (0.15, 0.32) | 1.27 (1.16–1.38) | < 10^ − 6 |
Market presence at destination (Yes vs No) | 1.06 (0.92, 1.21) | 2.89 (2.51–3.35) | < 10^ − 9 |
Urban destination (Yes vs No) | 0.67 (0.60, 0.74) | 1.95 (1.82–2.10) | < 10^ − 9 |
Human population at destination | 0.54 (0.32, 0.76) | 1.71 (1.37–2.14) | < 10^ − 4 |
Pairwise distance: urban destination compared to rural | − 0.17 (− 0.23 to 0.11) | 0.84 (0.79–0.89) | < 10^ − 5 |
All continuous variables were scaled to mean zero and one standard deviation. CI denotes Confidence Interval.
