This is actually much harder than expected, because of unbalanced designs. (An unbalanced design is when not all cells contain an equal number of observations.) We could support only balanced designs, throwing an InvalidOperationException when given an unbalanced design, but that is a bit unsatisfying. On the other hand, the appropriate way to handle unbalanced designs seems to be a point of statistical debate.

For now, just doing for balanced designs. Will introduce GLM to handle unbalanced designs in future.
