SAS Code for Transformation

Instead of one of the other transformation specification fields, here you can specify appropriate SAS syntax for transforming the variables.

Specify the transformation as a function of var[i]. For example, specify

var[i] = log2(var[i]+32);

to perform a shifted log base 2 transformation.

The transform expression can include any SAS statements, and is executed within a loop over the variables, which are stored in a SAS array. The specification is in this form to provide you with maximum power and flexibility to perform an unlimited number of transformations. If you are unfamiliar with SAS syntax (which is similar to the C language), please refer to documentation on the SAS language or seek assistance from a SAS programmer.

To Specify SAS Code for Transformation:

Type the appropriate code in the SAS Code for Transformation text field.
