Weekly number of estimated PCR confirmed cases with variant from week 0 to 13 and weekly prediction to week 18. A The weekly number of estimated PCR confirmed cases with variant from 28 December 2020 to 29 March 2021. The light blue dot represents sample estimates from empirical data, with the exact uncertainty bound (95% confidence intervals) represented by yellow error bars. The green line shows the simulated mean from the exponential growth model with bootstrap resampling experiments (n = 1000 times). The green shade shows the 95% confidence intervals derived from the parametric bootstrap method. B The weekly prediction of confirmed cases with variant. The green line shows the simulated mean from the exponential growth model with bootstrap resampling experiments (n = 1000 times). The green shade shows the 95% prediction intervals derived from the parametric bootstrap method. The number of PCR testing per week was assumed to be 10,000
