The role of children in the spread of COVID-19: Using household data from Bnei Brak, Israel, to estimate the relative susceptibility and infectivity of children
Fig 6
The log-likelihood as a function of the susceptibility and infectivity parameters.
Negative log-likelihood level curves for the parameters γ, δ, and three values of βaa. For smaller values of βaa the maximal-likelihood estimates of parameters γ and δ are larger. The white rectangle in the middle figure shows the 95% confidence region obtained using the bootstrap simulation.
