Table 2 Calibration methods and the number of parameters varied for each.
Calibration | Description | Parameters calibrated |
|---|---|---|
Constrained | A common set of natural history parameters is estimated for all countries | Common across countries: 4 natural history parameters kg; total parameters = 4 Unique to each country: 4 sexual behavior parameters per country; total unique parameters = 120 Total: 124 |
Immuno-varying | A common set of natural history parameters is fixed for all countries, but the mean immunocompetence varies from country to country | Common across countries: None (natural history (kg) fixed at prior means) Unique parameters: 1 natural history parameter per country (νc, the mean of the relsev distribution, estimated from a prior distribution of U(0.5, 1.5)) plus 4 sexual behavior parameters per country; total unique parameters = 150 Total: 150 |
Unconstrained | Natural history parameters free to vary from country to country | Common: None Unique: 4 natural history parameters (kg) for each country plus 4 sexual behavior parameters per country; total unique parameters = 240 Total: 240 |
