The following is a listing of all ratings
of players rated on both the Pan-Atlantic and ShogiClub24 rating systems
fulfilling the criteria given below. Of course, only those players whose
identities on ShogiClub24 are known to me could be included. The first
column is Pan-Atlantic, second is ShogiClub24.

All players listed have at
least 80 games on ShogiDojo, which reduces the effect of starting rating to
under 5%. All players listed have at least 30 games on Pan-Atlantic, where
starting rating plays only a tiny role and is in any case based on known
rank. Player must be listed on 2002 or 2003 Pan-Atlantic rating
list. No names are given in case some players prefer
anonymity.

There are 19 players on
this list. The average spread is 557.5 points, more than I expected.
We need to do a linear regression on the above numbers. If anyone can
perform this for us easily, we would appreciate it, so I don't have to rack my
brain trying to remember how to do it on my calculator or how to work
downloadable software.
