Table 3. Weighted values of model parameters for model M3 (direct transmission when viraemic cows calve and residual mosquito population in winter) and an introduction of RVFV on 2007-09-01 (weight: 0.73) or on 2007-10-01 (weight: 0.24).
| Parameter | Notation | Estimated value | 95% confidence interval | 
| Direct transmission when viraemic cows calve |   | 3.16 | [2.96–3.37] | 
| Relative abundance of vectors during the dry and cold season |   | 0.20 | [0.17–0.24] | 
| Vector/host ratio (vector production of 1 m2 of rice field) | Hv | 0.014 | [0.013–0.015] |
