Cody Kellner Points Index

The Cody Kellner Points Index (CKPI) began in 2002 as a basic formula that was based on winning percentages, conference winning percentages, and quality win points.

After that season, I felt winning percentages are not an accurate way to measure a team or the success of their season.

Over the next five years, I got advice for improving my system from people that are involved in the Bowl Championship Series as well as others that have advanced rating systems.  The advice I was given coupled with my own ideas and opinions helped me redevelop the CKPI to become known as an advanced computer ratings system such as the systems that are used in the Bowl Championship Series (BCS).  

The CKPI uses a least squares regression model and recalculates itself until ratings stabilize by use of simultaneous equations. These charactersitics are what make the CKPI known as an "advanced ratings system." 

The 2009 season will be the first time the CKPI will use results from the previous season as a component in the 2009 ratings.  The results of the 2008 season will be weighted at a decreasing rate as the 2009 season progresses. 

Individual statistics and location of game are not considered in the CKPI ratings.  The studies I have done in the last seven years indicate these variables do not make the CKPI any more accurate.

Please note the CKPI is based on the past and should never be used as a method of prediction.
