PLEASE Help! I have a dataset of customers who are flagged with whether they have viewed a film or not. Each row represents a customer. Each column represents a film, where a 0 or 1 states whether they have seen that film or not. I need to work out the correlation between these films i.e. if people watch X they are also most likely to have watched Y. A simple way would be to cross tab all variables so that I create a dataset with all films as a row and all films as a column, with the count of customers who had seen each film pairing. I don't know how to do this so I thought if my variables were continuous, a standard PROC CORR would give me all the information I need in matrix form i.e. the correlation coefficient and the frequency of customers. But how do I create this when my variables are binary? Or can anyone help me with creating the count matrix? ... View more
