Glicko Ratings:

 

This web site is intended to provide some background in the theory and practice of rating competitors in games and sports.

Two rating systems I have invented:

• The Glicko rating system, which is in the public domain
• The Glicko-2 rating system, an improvement on the original Glicko system. The system was under provisional patent, but is now in the public domain.

Coming soon (when I find the time!):

• History of common rating systems
• Rating tutorial
• Online rating calculators (including calculators for Glicko and Glicko-2)
• ... and much more!
