### NBA Power Rankings 2019-20

A novel application of generalized linear models is in the power rankings of sports teams. This blog will post rankings of all teams throughout the 2019-20 NBA season based on a Bradley-Terry model (with homeground advantage*) using head-to-head results up to the given date.

**Disclaimer**: Power rankings are for educational purposes only.

*From 17 December 2019 onwards, a Bradley-Terry model with team-specific homeground advantages will be fit. This is based on the extension by Huang & She (2020, to appear).

Western conference teams are in red; Eastern conference teams are in blue.
