Having fun with raw data

Here’s a plot the number of new test results per day for a number of states, normalized by population.  Notice anything odd?

Um, negative new tests in South Carolina yesterday??? and, three weeks ago, in Louisiana?  And what happened in Puerto Rico???  Are they un-testing people? Tossing out previous results? Alien Abductions(tm)?  Just plain tabulating errors?  I’m not sure exactly what is going on with this data set (the testing reports are from SC DHEC) but it shows you the perils of crunching numbers without looking at them – that would blow up any results derived from the number of people tested.  This is also why I don’t post charts every day, or plot every state/country (much less keep rolling Death Counters in the upper right hand corner of the screen updated in real time).  I wait to try to figure out what is going on first, and what the quality of the data is.  And as noted in a previous blog, it’s pretty wretched for a so-called industrialized country …

So let’s let the pandemic data simmer until next week.  Besides, there is an invest area in the West Pacific that might become a storm and impact the Philippines next week …
