    Snippet: We fitted the PLEC model with the nonlinear optimization method (i.e., the R-function 'nlsLM' introduced in the previous "The Model" section) to each of the 17 cities in Hubei province, each of the 34 provinces of China, as well as the whole China and worldwide infections datasets. The results were displayed in Table 1 (the PLEC model-fitting results) and Table 2 (test of the model performance). Since the model mostly failed to make meaningful pr.....
    Document: We fitted the PLEC model with the nonlinear optimization method (i.e., the R-function 'nlsLM' introduced in the previous "The Model" section) to each of the 17 cities in Hubei province, each of the 34 provinces of China, as well as the whole China and worldwide infections datasets. The results were displayed in Table 1 (the PLEC model-fitting results) and Table 2 (test of the model performance). Since the model mostly failed to make meaningful predictions of the infections outside China, we postpone the worldwide results to the "Discussion" section and here we focus on the results fitted to the datasets in China.
