How to find the minimum support in Apriori algorithm

Minimum support count is the % of the all transaction.suppose you have 60% support count and 5 is the total transaction then in number the min_support will be 5*60/100=3.

The support and confidence are measures to measure how interesting a rule is.

The minimum support and minimum confidence are set by the users, and are parameters of the Apriori algorithm for association rule generation. These parameters are used to exclude rules in the result that have a support or a confidence lower than the minimum support and minimum confidence respectively.

So to answer your question, when you say that: "For an example when support and confidence is given as 60% and 60% respectively what is the minimum support?" you probably mean that you have set the minimum support and confidence to 60 %.

I think that you are just confused by the terms.

My answer is coming a little too late, but I guess what Chanikag is asking is - "How to minimum support count when the support threshold is given as 60%". The Minimum Support Count would be count of transactions, so it would be 60% of the total number of transactions. If the number of transactions is 5, your minimum support count would be 5*60/100 = 3.
