Changes and Enhancements to SAS/STAT Software in V7 and V8

TRANSREG Procedure

The TRANSREG procedure now supports smoothing spline transformations in the MODEL statement. The SMOOTH option specifies a noniterative transform, and the SSPLINE option specifies an iterative smoothing spline transformation. You can specify the smoothing parameter with the PARAMETER= option or the new SM= option. The DESIGN option has been enhanced. Other new options in PROC TRANSREG provide control over output data set variable names and labels.
