About the Projections

The Price Guide provides several options when you are choosing which set of stats to base the dollar values off of:

CAIRO
by SG of Replacement Level Yankees Weblog

The CAIRO projections build upon the techniques used by Marcel, with a few enhancments. They use five years of data instead of three and are park-adjusted. They also include projections for minor league players. You can find more about them at RLYW. (The projected saves for 2010 are my estimates with input from the community.)

CHONE
by Sean Smith of Anaheim Angels all the way and BaseballProjection.com

More goes into the CHONE projections than I will explain here, but it has an excellent track record for accuracy. The projections include minor league players and players from Japan’s NPB. (The projected saves for 2010 are my estimates with input from the community.)

The Marcel the Monkey Forecasting System is the simplest projection system, using a weighted average of stats from the past three years regressed to the mean.

ZiPS
by Dan Szymborski of Baseball Think Factory

ZiPS is another system with a very strong track record for accuracy. Feel free to join the discussion of the projections over at the Transaction Oracle.

Composite
The Composite projections are simply an average of the others. It takes the edge off some of each system’s extreme predictions to give the most balanced values. Marcel is not included in the composite since it seems to weigh down the players with little MLB experience. I also adjust playing time based on my own expectations. (The projected saves for 2010 are my estimates with input from the community.)

Composite (Adj.)
This set is simply the Composite projections adjusted for projected playing time. This is available earlier than “Composite (CF)”, but is not as accurate.

Composite (CF)
This is the Composite projections adjusted for playing time by a snapshot of the Community Forecast. With hundreds of fans recruited to help predict playing time for players on their favorite teams, these should be much more accurate than the manual adjustment above.
