Does least squares regularization have to be iterative?

  1. Aug 3, 2008 #1
    Does a http://en.wikipedia.org/wiki/Tikhonov_regularization" [Broken] solution for least squares have to be iteratively solved? Or is there a way to perform regularization via linear algebra, the way linear regression can be done by solving the (XTX)B=XTy normal equations?

    Anyone know if this needs to be iteratively accomplished?

    Might there be someone who has a definitive answer to this issue? On whether regularization can be algebraically solved or not.
