Detecting and quantifying heterogeneity in susceptibility using contact tracing data
Fig 6
Parameter estimates for k and θ in the continuous case capture the true values and are highly correlated.
This plot shows the correlation in the parameter estimates for k and θ that determine the gamma distribution of individuals’ susceptibilities in the continuous case with different numbers of focal individuals F. The red dot represents 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). k = 0.592, θ = 0.626, and N = 5.
