Snow Crop Revisited

Critique of an earlier article by Kuehn in 1962 suggesting that a particular factorial analysis of customer brand buying could predict with accuracy repurchase trends.

Sums up that the factorial analysis by Kuehn is satisfactory only as a result of artificial assumptions whereby variance is ignored within groups – but when this factor is taken into account the model fails to adequately fit the data of Snow Crop – frozen orange juice.
