Feb 11, 2014 at 13:39 comment added Penguin_Knight Two billions is 2,000,000,000. The number in the 1st paragraph, 2,000,000, is two millions. Is that a typo or you have 2 billion customers, but only 2 million visits?

Feb 11, 2014 at 10:06 comment added D L Dahly To add a bit more to the above comment, a dummy variable refers to a set of mutually excluive categories, each coded as a 0/1. For example, if I have a variable called religion and there are 4 mutually exclusive levels coded as [1,2,3,4], I can turn that into four 0/1 dummy variables. This isn't what you mean, since clearly a person can go to more than one store, so you should edit your question appropriately, by replacing the word dummy with binary, or dichotomous.
