GAMLSS model fit statistics. Coefficients are exponentiated to provide linear scale rate ratios.
| Term | Rate ratio | P value |
| Penalised B-spline smoothing terms for the mean (expectation) parameter): | ||
| Baseline growth (day) | 1.004 | <0.001 |
| Added epidemic growth (day) | 0.996 | <0.001 |
| Penalised B-spline smoothing terms for the shape (overdispersion) parameter): | ||
| Baseline growth (day) | 0.991 | <0.001 |
| Added epidemic growth (day) | 1.038 | <0.001 |
| Akaike Information Criterion=748.3 | Residual df=48.1 | |
