>          Issue Type: Improvement

> The association rules modules works great but it could be improved by showing the count of candidates besides support.
> count = support * num_transactions
> The reason is that within the business you need to show the significance of a rule but you won't be able to do it just by support while you can do it by count (The number of times two items co-occured).
> One can manually multiply the number of transactions by support but working with big data, you need to compute the count first and then create a query over the assoc_rules result table to do the multiplication.
> It would be very nice to have the count within the assoc_rules table itself.
