Table 6 summarizes the point estimates and 95% confidence intervals of parameters, mean, and quantiles, where $\alpha ,\beta$ are the parameters of the Weibull distribution; Mean is the sample mean of incubation period, and Q _0.05, Q _0.25, Q _0.50, Q _0.75, Q _0.95, Q _0.975, Q _0.99 denote the 5%, 25%, 50%, 75%, 95%, 97.5%, 99% sample quantiles of the incubation period, respectively.
