Homemade statistical software

KDE, kernel based estimation

It's a series of lisp-stat objects and functions to do interactive kernel density (and regression) estimation. You will need Lisp-Stat running, but you don't need to be a hard lisp user to use it.

Also regarding kernel density estimation, a collection of interesting movies showing exact MISE for normal mixture a la Marron-Wand 92, may be found here.


A XLISP-STAT package to build interactive biplots. Biplots can also be obteined from our Biplot server (a quite primitive version is here)

fde version 99/10/11

Xlisp-stat programs to work with rich histograms, including several other piecewise linear estimators. The anchor position effect is considered. Some papers are included.
Some movies showing the effect of movingthe anchor position may be found here.

Some minor lisp-stat projects

board-proto version alpha1.0 2001/03/05

Implementing a board-proto XLISP-STAT object to include several graph windows in a single one. Documentation is inside the file. You'll NEED to have "more-graph-proto" (See next entry) in the same directory. Examples can be seen here and here.

more-graph-proto version pre-alpha 2001/03/05

Some additions to graph-proto to convey rich graphical information. This version is not fully tested and documented. Use it only as a companion to board-proto.

xfig.lsp version pre-alpha 2001/03/05

A method for graph-proto to translate graphical information to fig format. fig2dev can then translate it to many other graphical formats, including postscript. Xfig can also edit interactively fig files. (These are UNIX programs, some version for Windoze is available, but don't ask me about that).

This version is not fully tested and documented. USe only as a companion to board-proto. The project was started by Bernhardt Walter (do someone knows his e-mail address?) but current version is very different from the initial one.

symedit.lsp version 99/1/26 1.0

It contains code for a dialog window that shows the symbols currently in use in the xls workspace. The user can restrict the list in many ways: by packages, by variables/functions, using apropos, etc. For objects, a window shows slots, methods and other characteristics. It can be useful to explore/change values of global vars, to see what package produced what symbols, and to have some more fun with xlisp-stat.

denspol.lsp version March 1999

This is a program to show graphically how density functions and distribution functions are and do work together for a wide collection of parametric families of distributions. Load the file and type (start-density) to start it up.

dhelp.lsp version 99/7/20.- 1.01beta

This file implements a simple help system for calling lisp functions through a dialog window that shows the required (and optional) arguments.

It looks for the arguments in the function-lambda-expression. If the function does'nt have it (because it's compiled, for example) it requires the documentation string having a particular format. The first line must begin with "ARGS: " followed by the lambda list of the arguments in the same format as it appear in the defun. See the file intro for more details and examples.

tda.lsp version 99/7/19.- 0.01

Contain functions for data analysis grouped as: basic tools and vars basic datatable manipulation displaying datatable info This is made for my own use, it contain not enough documentation to be used by someone else...
