The retail market is dynamic in many dimensions - changes in product, changes in taste, changes in season.
Analysing the causes of changes in product volume has to take into account many factors - price, competitor activity, change in market structure, change in container size, cannibalisation of one product by another, from within the market segment or from outside.
Doing this analysis by hand is time-consuming, but doing it blindly automatically is not possible. A hypercube approach sets one view of the market in stone - the market is too dynamic for such an approach to work for long.
A method of analysis has been created which approaches the problem dynamically - find a trend and analyse it, which means finding both subtrends and super-trends. There will usually be many contributors to the effect, some independent of each other, some related.
