Can you post a brief overview of the method/algorithm you are using to compute OPR?

For example, are you forming the normal equations matrix N (square positive definite TxT matrix, where T is the number of teams) directly from the match scores data?

Or are you forming the 2MxT binary design matrix A (where M is the number of matches)?

Once you have N (or A), how are you using that to compute OPR?
