I am now a free agent on 'garden leave', open for "interesting" work in the quant / data science / ml space. Chicago, or possibly remote. Strong preference for compatibility with my adjunct position at U of Illinois. Any pointers? Please email edd@debian.org. Thanks!

Ever wanted to serve your #rstat code/models via http API? Curious on how to build high-performance backend micro-services which handle requests in parallel? Check out RestRserve - restrserve.org/ cc @TrestleJeff @opencpu

Fuck Perception! Left Panel: The two curves are PARALLEL, says @kjhealy in socviz.co/lookatdata.html. They just _seem_ not to be... That's wrong, I thought, and went on to plot vertical lines of the SAME LENGTH to produce the Right Panel...

That is a prime example of "volatility clustering": high values predict high values, low values predict low values. See Rob Engle (1982) and the very voluminous literature that followed (and rightly earned him a Nobel).
The S&P 500 went 94 days without a +/-1% change and then had 5 in 8 days.
