    Snippet: (4)Different Sample time selection. The sample period of standard regression is from January 1st, 2020 to February 18th, 2020. However, there are still many events that may have a significant impact on the number of cases during the sample period, such as the Spring Festival and lockdown of the city.

    Document: (4)Different Sample time selection. The sample period of standard regression is from January 1st, 2020 to February 18th, 2020. However, there are still many events that may have a significant impact on the number of cases during the sample period, such as the Spring Festival and lockdown of the city. In order to test whether the choice of time period has an impact on the regression results, further regression is carried out according to the sub-samples before and after Wuhan has been locked down. In each sub-sample , the effect of effective distance on the number of new confirmed cases is always negative, which implies that results are robust. the author/funder, who has granted medRxiv a license to display the preprint in perpetuity.
