Basic features when fitting quadratic response models
are available in PROC RSREG.

The RIDGE analysis of PROC RSREG supports an
automatic and a manual mode for RIDGE analysis.

Also, PROC REG supports the RIDGE analysys method
but only in manual mode: you have to explicitly code analysis
points, and the results are, without hypothesis testing,
written to the outest= dataset.

More info can be found in SAS/STAT User's Guide (RSREG),
or Technical Report P229 and  SAS/STAT Changes &
Enhancements through Release 6.11 (PROC REG).
