An experimental implementation of XLISP-STAT for MSDOS machines running Microsoft Windows 3.0 is now available. It has been tested and seems to work on a 286 with 2MB of memory; this is the minimal configuration. It must be run in protected mode. It is available for anonymous ftp from umnstat.stat.umn.edu (128.101.51.1) in the file pub/xlispstat/msdos/WXLSZIP.EXE This file is a self-extracting ZIP archive. Here is a brief description of the XLISP-STAT system: XLISP-STAT is based on a dialect of Lisp called XLISP. It is available for the Apple Macintosh, for workstations running the X11 window system under BSD UNIX (and perhaps System V with BSD enhancements), and for Sun workstations running SunView. A version for the Commodore Amiga is available as well. (And now there is also a preliminary version for MS/Windows.) The system is based on David Betz' XLISP 2.1, which is written in C. To facilitate statistical computations I have modified standard Lisp functions for addition, logarithms, etc., to operate on lists and arrays of numbers, and have also added a number of basic statistical functions. About two thirds of the additions are written in C; the rest are written in Lisp. Several basic forms of plots, including histograms, scatterplots, 3-dimensional rotatable plots and scatterplot matrices are provided. These plots support various forms of interactive highlighting operations and can be linked so points highlighted in one plot will be highlighted in all linked plots. Interactions with the plots are controlled by the mouse, menus and dialog boxes. An object-oriented programming system is used to make it possible to customize menus, dialogs, and the way plots respond to mouse actions. Source code for the UNIX version, which can be compiled without graphics, for X11 graphics, or for SunView graphics, is available by anonymous ftp from umnstat. Macintosh executables are also available by anonymous ftp. Source code for the Macintosh version is included in the UNIX sources. A tutorial introduction to the system is available. It is written primarily for the Macintosh version, but the differences to the UNIX version are minor. The tutorial is available as a set of LaTeX files from the ftp address above. More complete documentation is available as a book "Lisp-Stat: An object-oriented environment for statistical computing and dynamic graphics;" published by J. Wiley & Sons. If you do not have access to anonymous ftp, you can obtain the source code and documentation from the statlib archive.
