Detecting and quantifying heterogeneity in susceptibility using contact tracing data
Fig 5
Parameter estimates for pA, pB, and fA in the discrete case capture the true values and are highly correlated.
The plots show the correlation in the parameter estimates for a) pA vs. pB, b) pA vs. fA, and c) pB vs. fA with different numbers of focal individuals F. These are the parameters that determine the distribution of individuals’ susceptibilities in the discrete case. The red dots represent the true parameters used to generate our simulated data, and the gray dots depict 1, 000 parameter sets from our posterior distribution for F = 50 (light gray), 200 (medium gray), 1000 (dark gray), and 5000 (black). pA = 0.748, pB = 0.125, fA = 0.2, and N = 5.
