Empiric (dots) and stretched exponential estimated probability density function Prob(R₀) = a exp[–(R₀/b)^c] (solid line) (16) of R₀ for the cases of Toronto (a = 0.186, b = 0.803, c = 0.957, after control measures had been implemented), Hong Kong (a = 0.281, b = 1.312, c = 0.858), and Singapore (a = 0.213, b = 1.466, c = 0.883) obtained from our uncertainty analysis. The distribution for the case of perfect isolation (l = 0, a = 0.369, b = 0.473, c = 0.756) is shown as a reference.
