Bayesian coalescent inference of full-length NA sequences from 2009 H1N1 Influenza A virus strains.
| Group | Parameter | Valuea | HPDb | ESSc |
|---|---|---|---|---|
| 62 NA sequences | Log likelihood | -2601.35 | -2616.89 to -2586.07 | 1401.12 |
| Mean Rated | 7.84 × 10-3 | 7.59 × 10-3 to 1.43 × 10-2 | 126.75 | |
| Codon 1e | 0.97 | 0.67 to 0.95 | 29387.19 | |
| Codon 2 | 0.51 | 0.25 to 0.79 | 40307.00 | |
| Codon 3 | 1.51 | 1.17 to 1.86 | 26291.08 | |
| Expansion Growth Ratef | 66.43 | 0.38 to 503.70 | 206.45 | |
| Root age (days) | 324.99 | 130.84 to 644.01 | 163.42 | |
| MRCAg | August 17th, 2008 | September 27th, 2007 to March 9th, 2009. |
aIn all cases, the mean values are shown. b HPD, high probability density values. c ESS, effective sample size. d Mean rate was calculated in substitutions/site/day and transformed to substitution/site/year. e Contribution of each codon position to the mean rate. f Expansion Growth Rate was calculated in number of new infections/individual/day and transformed to number of new infections/individual/year. g MRCA, day of the Most Common Recent Ancestor.
