More on Correlating COVID Vax Status with Traffic Risk

I continue to rant about that correlation paper on COVID “vaccine hesitancy” and traffic risk. I leave the statistical critiques to others (and I drop the links below and to my prior post), but the correlation can be rock solid and the conclusion still be completely off. Be careful of the over-interpretation of correlative studies.STUMP - Meep on public finance, pensions, mortality and more is a reader-supported publication.

And a lot of the spurious correlations involve death.Agatha Christie’s Mr. Parker PyneAs the Amazon editorial description is a bit inaccurate, let me share one of the reader reviews:After reading two of Agatha Christie's short stories featuring the very unconventional private investigator, Parker Pyne, I knew I had to read more, so when I came across this collection, I grabbed it.Pyne relies upon his thirty-five years in a government office compiling statistics to help him solve any case that's presented to him. Some of the short stories revolve around people who respond to his advertisement in The Times, but Pyne also travels to more exotic climes, such as Jordan, Syria, and Iran and finds himself solving puzzles in those countries as well.Don’t drive like a maniac!
