I'm used Excel 2007 Data mining add in.
What the meaning is 'Importance'. And there isn't lift?

Importance of a rule measures how good the association of two items in a
rule is, and also the direction of the rule. Let's say you have a rule A=>B.
Importance of 0 means there is no association between A and B; positive
importance means that the probability of B goes up when A is in the basket,
and negative importance means that the probablity of B goes down when A is
in the basket.
You do not have lift chart for Association Rules.
