The initial value C0 of the logistic equation could be used as an indicator of the early number of cases, reflecting the level of early contamination from Hubei province as the epicenter of the outbreak. To support this proposition, the upper panel of Fig. 4 plots the estimated C0 as a fu...
As described in the introduction, the cdf and pdf of the HLIR distribution with the vector of parameters 𝜑=(𝛼,𝜆)φ=(α,λ) is obtained by inserting Equation (1) into Equation (2) and Equation (3), i.e., 𝐹(𝑥;𝜑)=1−[1−𝑒−(𝛼𝑥)2]𝜆1+[1−𝑒...
