Immigration rate (λj) curves for the models with different prior sets 1, 2 and 3 for the Côte d’Ivoire data. The model with prior set 1 estimates the immigration rate almost as constant, hence there is little dependence with time (age). The immigration rate curves for the models with prior sets 2 and 3 (best fitting model) show that the immigration rates in the youngest age groups are higher and decrease rapidly to an asymptote.
