Could anyone please suggest how to data cluster analysis? I have a large set of multi-dimensional data (300 children prefer 2-3g of sugar in their breakfast cereal, whereas only 100 prefer 1-2g, etc) and I want to break the data up into blocks that minimize the number of different types of cereal I should create, while capturing the maximum amount of the market. I expect there is some least-squares way of doing this, can anyone suggest a concrete example of how to this in Maple10? Thanx
