Hello everyone! I have a keen interest in both statistics and chess and I wanted to do some statistical analysis of players ratings between Lichess, chess.com USCF and FIDE. I am asking for as much participation as possible. I will compare rating differences between all four using multiple linear regression with SAS.
To collect the data I will be asking for your chess.com username, lichess username, FIDE ID, and USCF ID. In order to participate your rating must not be provisional at any one of them but it is not required that you have all of the above (just a minimum of two). Using some data collection tools I am able to easily link the above although I will manually have to get the chess.com ratings. Please only link your FIDE or USCF ID if you believe it accurately represents your playing strength (aka you have played recently if the last tournament you played was in 1999 it doesn't make much sense to be included for that rating).
Using the data, assuming enough is collected for a good sample, I can estimate a players FIDE, USCF, Lichess or chess.com rating given a series of any other ratings.
Participation is voluntary! You are welcome to PM me your USCF ID or FIDE ID if you don't want it public. I will not share that portion of the data. You are also free to post it below.
