Hypothesis Identification in the Case of the Missing Cell
Earl Jennings, Joe H. Ward · The American Statistician · 1982
Using a paper by Freund as a context, the authors argue that many of the perceived difficulties in missing cells problems result from overparameterization. A full-rank approach, with special emphasis placed on the importance of stating hypotheses in terms of easily understood estimable parameters, is suggested as a way of reducing confusion.
