SSAS Wrong Lift ?

    Question

  • Hello,

    There's something I don't understand with Lift calculation in SSAS using a association mining model.

    Example :

    Number of transactions : 18 396

    Number of transactions including "Bananas" : 2 052

    Number of transactions including "Apples"  :  2 152

    Number of transactions including Apples & Bananas : 807

    SSAS node lift for the rule Apples & Bananas: 0,4779

    ==> Lift should'nt be :  Pr(A&B) / (Pr(A) * Pr(B)) = 3.36 ???

    thanks
