Dear dr Grosse, Thank you for your recent reply to my query on the availability of my GCVSPL package from research!netlib. Pursuant to my letter by ordinary mail of today together with the original paper on the package, I am sending you in the next E-mail message the GCVSPL package plus a copy- right notice (it appears that the package is available from anl-mcs). Would you kindly include this material in NETLIB under MISC, pending further decisions on the installation of a separate SPLINE category? Thank you for your assistance in this respect, Sincerely Yours, (dr ir) Herman J.

Anyway, my colleagues Doug Bates, Mary Lindstrom and Brian Yandell and I are putting the final touches on GCVPACK (to appear, Commu. Stat.) and I think they will think it is a good idea. By copy of this I'm asking them if its ok and, if so, for Mary Lindstrom to send you what you need when its done.

We are currently in the last stages of prepairing a new version (release 2) of gcvpack which has some new features and cleaned up code. I will send you a copy of release 2 when it is ready (about 2 weeks). From: lindstro@stat.wisc.edu (Mary Lindstrom) To: ehg.swift%btl.csnet@CSNET-RELAY.ARPA Subject: gcvpack The second (and last) release of Gcvpack is done. Our next three messages will contain the source for Gcvpack - release 2. Also, we will be sending you the revised version of the technical report which documents the code, "GCVPACK-ROUTINES FOR GENERALIZED CROSS VALIDATION", by D. Bates, M. Lindstrom, G. Wahba and B. Yandell, University of Wisconsin-Madison TR No. 775 (rev.), October, 1986. file approximate number of lines ------ --------------------------- gcv1 2662 gcv2 2500 gcvdoc 358 To create the Gcvpack source, put the text of each of the messages listed above into files and execute them by `sh filename'. Several fortran source files, a Makefile, sample input and output files, and two documents will be created. The Makefile will indicate which fortran routines you should have received. The Makefile assumes a public library containing Linpack accessible by -llinpack. The fortran source files include all the Gcvpack subroutines along with three test drivers (inteqn.f, testptpss.f and testtpss.f) and two routines called by inteqn.f (mktpar.f and mkxys.f). The test drivers take input data from input files (the appropriate .in files) and return output which should be compared to the test output files (the .out files). Included in the files we are sending you is a list of changes from the first to the second release and documentation for the information numbers. These two documents are also in the second version of the technical report. If you have problems or questions, please mail details to gcvpack@stat.wisc.edu We may be contacted individually as follows: bates@stat.wisc.edu - Douglas Bates lindstro@stat.wisc.edu - Mary Lindstrom wahba@stat.wisc.edu - Grace Wahba yandell@stat.wisc.edu - Brian Yandell From bayes.stat.wisc.edu!wahba Tue Jun 13 22:59:23 CDT 1989 Received: from bayes.stat.wisc.edu by pokey.cs.wisc.edu; Tue, 13 Jun 89 23:01:05 -0500 Date: Tue, 13 Jun 89 22:59:23 CDT From: wahba@bayes.stat.wisc.edu (Grace Wahba) Message-Id: <8906140359.AA23400@bayes.stat.wisc.edu> Received: by bayes.stat.wisc.edu; Tue, 13 Jun 89 22:59:23 CDT To: ehg@research.att.com Subject: rkpack (first message) Cc: gu@bayes.stat.wisc.edu, wahba@bayes.stat.wisc.edu ehg@research.att.com Dear Eric --here is rkpack. Below is the new entry for GCV for the index. I have added O'Sullivan, when I sent you the last revision I was not aware that O'Sullivan's code was in the GCV library, I found that out by reading the INDEX FOR GCV; and I have added Gu, which is rkpack. In the next mail message I will send you the rkpack file. It is a bundle which includes instructions, the code and the latex file for TR 857 which constitutes the documentation. We are sending you a hard copy of TR 857 as well as the other two references listed. Thanks much. Revised GCV entry for the INDEX: ----------------------------------------------------------------- GCV software for Generalized Cross Validation from: O'Sullivan, Woltring (univariate spline smoothing), Bates, Lindstrom, Wahba and Yandell (multivariate thin plte spline smoothing and ridge regression), Gu (multiple smoothing parameters). The rkpack entry for INDEX FOR GCV is -------------------------------------------------------------------------- rkpack C. Gu, University of Wisconsin-Madison [gu@stat.wisc.edu] Rkpack embodies two generic algorithms for computing smoothing spline models. The smoothing parameter(s) are chosen by generalized cross validation (GCV) or by generalized maximum likelihood (GML). The kernel of the algorithms is based on Householder tridiagonalization with distributed truncation. The user interface is through two drivers which handle single and multiple smoothing parameter least squares problems respectively. The description of the drivers and their applications in thin plate splines and additive and interaction splines is documented in UW-Madison Statistics TR 857, which is made available as a LaTeX file. More technical details can be found in the references cited in TR 857, especially Gu et al.(1988) and Gu and Wahba(1988). The materials are bundled for UNIX users with access to LaTeX facilities and Ratfor preprocessor. On receiving the bundle, create a directory and unbundle the materials in the directory. Run `latex rkpk.tex' twice to produce the `rkpk.dvi' file, and consult the local expert to print out the `rkpk.dvi' file to get UW-Madison Statistics TR 857. Run `make' to create the library. Linpack (including Blas) and Blas-level-2, both available from netlib, are needed in compiling the executable which calls Rkpack routines.

It got to me fine, but experience indicates that such large files aren't accepted by some mailers. So I've taken the liberty of splitting out rkpk.tex into a separate file, making appropriate changes to the index file and the bundled README. Please let me know if this is ok with you and I will ship the files to Argonne.
