I am starting with market basket, so I have been practicing with datasets available in the internet.
I have used the 'retail' data set available at http://fimi.cs.helsinki.fi/data/retail.dat
, which is in the dense format.
But since I will get my own data from a friend's shop, my question is:
What is the best format for a market basket analysis with RM?
PS: I will probaly use Apriori and FPGrowth.
