Release of Wagon and Argos Junior

Jason

Greetings,

I'd like to announce the release of the following statistical
software:

1. Wagon: https://chi-square-works...
Wagon is a free, open source implementation of Classification And
Regression Trees. It is released under a two-clause BSD license.

2. Argos Junior: https://chi-square-works.co...
This is a free dynamic graphical data analysis system with a
unique graphical auditing functionality. Argo Junior's plots
form a live user interface to the data being explored (rather
than a mere static display of data). This unique property of the
plots lends itself easily to a universal series of steps for data
analysis. Users first launch a tool that generates a plot. They
then inspect that plot for interesting patterns and paint such
patterns to select them. Finally, they siphon the selections out
and loop back to launch a tool to examine the selected
observations. We commonly refer to this process by the term
"LIPS loop" (Launch-Inspect-Paint-Siphon loop).

Graphical auditing records LIPS loop interactions into a script
invokable on other data sets. With no programming experience at
all, even novice users can use graphical auditing to replicate
and log complicated data analysis without human error. By taking
the burden of repetitive data analysis off users, graphical
auditing allows users to actually concentrate on understanding
the patterns in their data.

Wagon and Argos Junior are implemented in Common Lisp. So far, we have
run Wagon on Allegro Common Lisp, CMUCL, SBCL, and Lispworks. It
should run on other Common Lisp implementations. Right now Argos
Junior only runs on Microsoft Windows (it ran on Linux a few years
ago). SBCL runs more than 99.99% of its code and Lispworks runs the
other tiny portion. We use GTK+ through the wonderful CLG bindings by
Espen S. Johnsen.

Feedback and comments will be greatly appreciated. Feel free to drop us
a line!

Best wishes,

Jason
