I present an update to my previous post. Starting May 17, 2020 the DC Mayoral Office began releasing testing information by neighborhood on their coronavirus data portal.

After moving to DC last year, PoPville has been a personal favorite for local scoop. A post on May 11, 2020 captured my attention.

I present code to identify areas of a spatial segregation model that exceed our null expectations using the relrisk function in the spatstat package and an assumption of normality of the estimated probabilities.
