    Hi all,

    I'm using the K2 algorithm (Cooper & Herskovitz, 1992) to learn a bayesian
    model from data. The point is that in this algorithm I need to compute the
    fatorial of Nijk (the number of cases in which a variable xi has the value
    vik, and the parent of x is instantiated as wij). When the number of cases
    (in the database) is big, I can't compute this fatorial.
    I was wondering if anybody have already faced this problem and have any
    sugestion.

    Thank you in advance,

    Estevam.
