The PRINQUAL Procedure |
If the transformation is monotonic and a constant transformed variable results, the procedure multiplies the target by -1 and tries the optimal scaling again. If the transformation is not monotonic or if the multiplication by -1 did not help, the procedure tries using a random target. If the transformation is still constant, the previous nonconstant transformation is retained. When a constant transformation is avoided by any strategy, this message is displayed: "A constant transformation was avoided for name."
