COVID case death rate

[akburnham]

The case death rate has large fluctuations due to the timing of the time lag between new cases and new deaths. The current plot uses a 10-day time lag, but the data suggest something more like a 21-day delay on average between the two reportings. Obviously, the time lag depends on all sorts of reporting issues as well as inherently being a distribution. That being said, it seems that the empirical time lag would be the best option for dividing these two curves.
