Transform Variables Node

On page 168, under the Output tab, I reference to the fact that SAS Enterprise Miner will automatically set the transformed variable to missing when the LOG transformation is applied to the variable of the value of zero. It should be noted that this problem has been resolved by SAS with a downloadable service patch. From the table listing, notice that some of the transformed YOJ values are set to zero from the user-defined transformation as oppose to the standard transformation that sets the transformed values to missing with regard to the values that are undefined from the logarithmic transformation. However, it should be noted that SAS has provided a downloadable service patch to resolve this problem.
