COVID 19 cases data from Johns Hopkins, augmented and reformtted
This dataset processed and augments the COVID-19 data provided by Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE). The source data is checked into Github daily. and is collected from a variety of sources.
This dataset reformats the data into tidy format, with dates expressed as values instead of column headings, and adds several fields that are useful for analysis.
The 'rate_t5d' column is the growth date from 5 days before the observation to the observation. For example, for a row with a current observation of value x_5, and a past observation of x_0, the rate_t5d is calculated as e^((log(x_5)-log(x_0)) / 5)-1 . The result is that x_5 = x_0 * (1+rate_t5d)^5, and rate_t5d from the previous 5 days
