[R] Study design question; MLB; pay and performance.

[N. S. Miceli, Ph.D.]

Dear List Members,

I am in the process of designing a study examining pay and performance 
in Major League Baseball across several seasons, and before I get too 
deeply into it, I'd like to ask whether the group members think that 
performance across seasons is independent, or if it needs to be treated 
like a time-series variable so that lack of independence can be controlled.

Any ideas or considerations that need to be taken into account would be 
appreciated.

Regards,

Nick Miceli
