Tabs March 2016

Well the time has come to clean up tabs.  If I bookmark them I’ll never see them again, so I might as well share them.
So again I looked at microdata from the American Time Use Survey from 2014, which asked thousands of people what they did during a 24-hour period. I used the data to simulate a single day for 1,000 Americans representative of the population — to the minute.

More specifically, I tabulated transition probabilities for one activity to the other, such as from work to traveling, for every minute of the day. That provided 1,440 transition matrices, which let me model a day as a time-varying Markov chain. The simulations below come from this model, and it’s kind of mesmerizing.


Take a second look at these.  Amazing.

I dunno about best in the world, but this kitchen does have some pretty killer features that aren’t obvious at first:

Reddit title was “Smearing time like butter.” Not even going to try to improve that.  Takes a little while to get really into it.
