Description:
The Cochrane Orcutt procedure should optionally calculate the Durbin Watson test statistic on each iteration and save it to an array in a similar way to how the betas of each iteration are done currently.

Further- Cochrane Orcutt should terminate early if Durbin Watson test statistic is within acceptable range.
