Before revision:   Using the data provided by China authority , we show our one-day prediction errors are almost less than 3  %DIF < . The turning point and the total number of confirmed cases in China are predicted under our model.
After revision:  Such an approach is more adaptive than traditional static SIR models and more robust than direct estimation methods. Using the data provided by China authority , we show our one-day prediction errors are almost less than 3  %DIF < . The turning point and the total number of confirmed cases in China are predicted under our model.
