Interesting topic in Spatial Statistics 1 today: Just where exactly is the ‘center’ of something? There are a dozen different ways to pick one from a multivariate dataset. I thought I’d toy around with weighted averages to see if I had the concept figured out before I tackled the weekend’s homework. Here’s the approximate center of the transit system(s), weighted for trip origins and destinations as of the most recent data I have.
Pro-tip for cartographers: When your data is simple, throw in gratuitously pretty and engrossing things like elevation and hillshades as points of reference.
