TROUBLES.!!! 5508 ...trouble shooting advice
RXridge provides a user-friendly text-mode Windows/Menus/Prompts
interface for normal-theory, maximum-likelihood "shrinkage
regression" computations (ridge/BLUP/Bayes/Stein) and interactive
CGA graphics TRACE displays. RXridge can now handle "exact"
(numerical) singularities as well as statistically ill-conditioned
datasets.
MPG0.CRX 1256 \ Output files from RXridge for input to
MPG0.DRX 1255 \ either RXtraces of PathProj...
MPG0.ERX 1257 \
MPG0.IRX 1257 / These 6 files describe the shape Q=0
MPG0.PRX 1146 / shrinkage path on a subset of Hocking's
MPG0.RRX 1257 / gasoline mileage data;
RXTRACES.EXE 57055 ...interactive ridge TRACE displays
RXTRACES.DOC 34635 ...March 1993 shareware ASCII documentation
RXtraces makes interactive CGA graphics displays of 5 types of ridge
TRACES, including estimates of: regression coefficients, scaled mean
squared errors, excess (ols minus ridge) eigenvalues, inferior
direction cosines, and the overall shrinkage pattern. RXtraces is
ideal for ridge "training" applications in which students simply
review RXridge or RelaxR outputs across a spectrum of previously-
computed numerical examples.
MPG.PRX PRX 1146 \ Output files from RXridge for input to
MPG.XRX XRX 1251 > PathProj...
MPG.YRX YRX 355 / (Again a subset of the Hocking data.)
PATHPROJ EXE 62062 ...interactive ridge Path Projection
PATHPROJ DOC 46292 ...May 1993 shareware ASCII documentation
PathProj makes interactive CGA graphics displays of the projection
of ridge shrinkage path statistics (regression coefficients and
inferior direction, regressor coordinates) onto any 2-dimensional
linear subspace (specified via orthogonal direction cosine vectors.)
Literally "watch" the inferior direction change as you step along
the ridge shrinkage path!

ASP wants to make sure that the shareware principle works for you. If
you are unable to resolve a shareware-related problem with an ASP member
by contacting the member directly, ASP may be able to help. The ASP
Ombudsman can help you resolve a dispute or problem with an ASP member,
but does not provide technical support for members' products. Please
