[R] nonlinear MVA in R/knitr
http://rpubs.com/deleeuw/83572. The paper uses monotone B-splines and majorization in an R function that implements nonlinear generalizations of PCA, multiple regression, image analysis, SEM. And much more. This extends methods in the CRAN package `aspect`. The theory has been around for 30 years but the technical improvements using R, RStudio, knitr are impressive, if I say so myself.

[R] [R-pkgs] homals package and core loop
The homals package http://www.jstatsoft.org/v31/i04 will get a major programming overhaul. This will take some time, but what's a few years on a 40-year project. Suggestions from the audience are welcome. homals() has a core loop over the m variables in which 1. tapply is used to compute category quantification (centroids) 2. category quantifications are then adjusted to satisfy the rank and level constraints The idea is to replace 1 by least squares fitting of a B-spline and to adjust 2 accordingly. The core will be re-programmed in C and/or FORTRAN (sometimes using existing routines), and the loop over variables will be parallelized using OpenMP or Grand Central Dispatch. For ordinal variables this requires some alternative quadratic programming routines to be linked in (which could then also become part of the isotone package). In addition the basic homals code will have object (individual) weights (minor addition) and the prehom routines (from the jacobi package) will be added. Because of the use of B splines the variables in homals will no longer be all factors, some can now be numerical (continuous). Otherwise the package will keep its many analysis options (multi-set non-metric canonical analysis, non-metric discriminant analysis, non-metric regression, multiple correspondence analysis, non-metric principal components analysis, non-metric additive conjoint analysis) and its many plot options.

[R] FYI: APL in R
http://idisk.mac.com/jdeleeuw-Public/utilities/apl/apl.R Dedicated to the IBM 2741. Implemented for general multidimensional arrays: drop, take, reshape, shape, rank, select, generalized inner product, generalized outer product, representation, base value, join, expand, reduce, scan, member of, ravel, compress, tranpose, rotate Basically, the APL-I part is complete, and after some testing and clean-up this will be 1.0. In the code there is a small section explaining the relation between aplTP(), the APL transpose function, and the (less general but more natural) aperm() from R. I may decide to add some extensions from APL-X, APL-2, J, Sharpe APL, APL 2000, Dyalog APL, later on. In any case, the current code adds a lot of array operations (and even matrix and vector operations) to R. Although this is all prefix and no infix, we could easily recreate some of the infamous APL one-liners that nobody can possibly understand or reproduce. === Jan de Leeuw, 11667 Steinhoff Rd, Frazier Park, CA 93225 home 661-245-1725 mobile 661-231-5416 work 310-825-9550 .mac: jdeleeuw +++ aim: deleeuwjan +++ skype: j_deleeuw === I am I because my little dog knows me.

[R] R-outlet: Journal of Statistical Software
The Journal of Statistical Software was founded by Jan de Leeuw in 1996. Currently, there are 26 volumes with 260 aricles and the journal publishes about 4 new volumes per year. The web address is www.jstatsoft.org. All articles are pdf files, since 2005 all produced from JSS LaTeX templates. JSS is edited by Jan de Leeuw, since 2005 jointly with Achim Zeileis of the Wirtschaftsuniversität Wien. Formally, since 2004, the publisher is the American Statistical Association, but all editorial and IT work is done at UCLA Statistics. JSS is a Ruby on Rails interface to a PostgreSQL database, maintained by Jose Hales Garcia of UCLA Statistics. The journal is hosted on the UCLA Statistics servers. JSS is now the computational statistics journal with the highest Thomson ISI impact factor (13th place out of 91 statistics journals) and the highest immediacy index (2nd place out of 91 statistics journals).

x^m_{i_ms}
with arrays of arbitrary dimension. Reminded me of the good old APL
days. I could not find this in the archives, but if it's already there,
I would appreciate if someone let me know.

[R] it looks like ...
in 2007 we will publish seven volumes of JSS (four of them special volumes). Volume 18 Spectroscopy and Chemometrics in R Volume 19 regular Volume 20 Psychometrics in R Volume 21 regular Volume 22 Ecology and Ecological Modeling in R Volume 23 is being started, it is a regular volume, and may not fill up completely. Volume 24 is 'Statistical Modeling of Social Networks with statnet' -- it is not a Foometrics volume but can serve as another model for special volumes. Another Foometrics volume (Political Methodology in R, guest editors Altman and Jackman) will be out early 2008. If you have suggestions about special volumes of either type (Foometrics with R or Statistical modeling of X with R/Stata/SAS/... package Y or Statistical modeling of X with R/Stata/SAS/...) drop me an email. For a special volume we need a guest editor and 6-10 submissions. I sincerely hope that the year 2007 was a local maximum and that we will return to four or five volumes per year in 2008. === Jan de Leeuw; Distinguished Professor and Chair, UCLA Department of Statistics; Director: UCLA Center for Environmental Statistics (CES); Editor: Journal of Multivariate Analysis, Journal of Statistical Software; US mail: 8125 Math Sciences Bldg, Box 951554, Los Angeles, CA 90095-1554 phone (310)-825-9550; fax (310)-206-5658; email: [EMAIL PROTECTED] .mac: jdeleeuw +++ skype: j_deleeuw +++ homepage: http://www.cuddyvalley.org - No matter where you go, there you are. --- Buckaroo Banzai http://gifi.stat.ucla.edu/sounds/nomatter.au - [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
