Minimum Support Count

Define a minimum support count to ensure itemsets appear frequently enough in transactions to be considered significant.

Minimum support count defines minimum threshold in transactions that each rule must satisfy. When the number of transactions is unknown, the support percentage threshold parameter can be tricky to set appropriately. For this reason, support can also be expressed as a count of transactions, with the greater of the two thresholds being used to filter out infrequent itemsets. The default is 1 indicating that this criterion is not applied.
