Bayesian phylodynamics of avian influenza A virus H9N2 in Asia with time-dependent predictors of migration
Fig 5
Predictors of time-dependent population dynamics of H9N2 influenza viruses within 12 countries/locations in Asia.
Coefficients and indicators as in Fig 4 when estimating the effective population size of H9N2 AIVs (a) without and (b) with considering the effect of virus sample size included as a distinct predictor. The 50% prior mass was specified on no predictors being included. Bayes factor support values of 3 and 20 are represented by a thin and thick vertical line respectively in the indicator plot. Poultry production positively contributes to virus population size. When the number of samples through time in each location is also used as a predictor, the effect of poultry production is much less pronounced for the virus sampling may have been approximately proportional to effective population sizes.
