Well, when it comes to surrogates, you actually had to make a choice:
1) Change the negative team number (surrogate) to positive and do the computation. When a team plays as surrogate, the alliance score will count against their OPR.
or
2) Leave the team number as negative. The surrogate will be considered a completely separate team, and will be assigned its own OPR
or
3) Replace negative team number with 0 (or some other placeholder). Team 0 will be assigned its own OPR, even though it represents contributions from several different surrogate teams
or
4) Ignore the match entirely (leave the entire match out of the design matrix). The alliance scores for that match will be omitted from the remaining non-surrogate teams in the match.
or
5) Include the match, leaving the surrogate team out of the design matrix
I realize some of the options above are poor choices.
I think Option (1) is the best approach. Is that what you did?
