New and upgraded Xlisp-Stat code in
ftp.stat.ucla.edu:/pub/lisp/xlisp/xlisp-stat/code/homegrown
Look in the following subdirectories. Some of this code is incomplete,
in the sense that some parts are unfinished. It will be updated whenever
another part is ready, or whenever substantial changes of any kind are
implemented.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
01/20/95 spatial/ has code for different types of variogram estimates
By Stan Bentow, Dave Afshartous, and George Michailides.
01/20/95 plotters/ has a useful upgrade to spin-plot-proto by
Jason Bond.
01/18/95 modules/ has a new selection of modules and demos for
introductory statistics teaching. By Jason Bond and
Jan de Leeuw.
01/13/95 help/ has a large on-line help system for xlisp/xlisp-stat
by Jan de Leeuw. IN PROGRESS.
01/12/95 IO/stem-and-leaf has a stem-and-leaf plot with sliders. By
Jason Bond.
01/05/95 robust/ has code for Rousseeuw's S_n scale estimate. By Jason
Bond. Q_n IS COMING.
01/05/95 robust/lms has code for Stromberg's exact algorithm to do
Least Median of Squares estimation. By David Betz.
12/30/94 optimize/ has Bruno Haible's CL simplex method, adapted to
Xlisp by David Betz.
12/25/94 niceties/ now has list-from-string.lsp which takes a string
and cuts it in pieces defined by the separating
characters in charbag. Does a post-operation on each member
(capitalize, reverse, whatever).
12/23/94 IO/ has write-profile.lsp which takes a list of lists with
category labels for a number of variables, and writes a string matrix
will all possible profiles. The file also has a function
write-latex-table which takes a xlisp array of strings and
writes it to a file with LaTeX table/tabular environments.
12/19/94 sem/ has code for maximum likelihood and least squares factor
analysis, for image analysis, and for minimum trace factor
analysis. By Jan de Leeuw.
12/19/94 smoothers/ has code and a manual for Jerry Friedman's
variable span supersmoother. By Jason Bond and Afshan Tabazadeh.
12/19/94 combinatorial/ has code by David Betz to generate all
choices of m out of n lexicographically.
12/19/94 optimization/ has routines to compute roots of polynomials
of degree lte four using the classic algorithms (by Sona Vartanian).
12/10/94 bootstrap/ has the bootstrap for stationary observations, by
Jan de Leeuw.
12/10/94 robust/ has a growing list of robust location and scale estimates,
by Jan de Leeuw.
09/06/94 mcmc/ has code by Jan de Leeuw for Adrian Raftery's technique to
estimate the number of iterations of the Gibbs sampler.
09/02/94 bootstrap/ has the balanced bootstrap, by David Betz.
