com.cloudera.science.mgps.QFunction
An implementation of the Qn function described in DuMouchel and Pregibon's 2001 paper, "Empirical bayes screening for multi-item associations". Used by the {@link EBGM} and {@link EBCI} Pig functions for scoring the item tuples.

    this.target = target;
    this.alpha1 = alpha1;
    this.beta1 = beta1;
    this.alpha2 = alpha2;
    this.beta2 = beta2;
    this.q = new QFunction(new NFunction(alpha1, beta1),
        new NFunction(alpha2, beta2), p);
  }
