-*- mode: text -*- Common Lisp Stat: After a few false starts, I (Tony Rossini) finally know how I want to proceed. First, we update CLS. Then, continue with TSL. Separation is needed, so that we can make everything separate. We are working with SBCL and CLISP implementations so as to keep a wide range of target platforms as well as to maintain ANSI CL as close as possible. This challenges the system by targetting two more common CL implementations (compiled, and byte-compiled). Design: (see "orig file dependencies" below for original design docs through code). ------ lsobject : package containing prototype object system data : package from which all data objects are built. data should provide compound objects, pulling from all potential data structures, so that optimization : maximization linear-algebra : merges matrix data structures, numerical linear algebra work <specialty routines> regression nonlin glim gee bayes-regression ls-user : ============ File Dependencies from 9 Feb 2007 Package lisp-stat-object-system self contained Package lisp-stat-fastmap self contained, new.

This is Lisp-Stat 1.0 Alpha 1, a first attempt at producing a Common Lisp version of Lisp-Stat. This version contains NO graphics, but should implement all the non-graphical facilities of Lisp-Stat. The implementation uses C code from XLISP-STAT for linear algebra and probability distributions, so this code is dependent an a CL's foreign function interface. At this time, three CL's are supported: AKCL (at least verision 1-600) for UNIX systems, Franz' Allegro CL for UNIX systems, and Macintosh CL (version 2.0b1). Separate README files describe each version On A DEC 3100 or 5000 the AKCL version of Lisp-Stat runs about half as fast as xlispstat on a standard battery of tests if xlispstat is given an (expand 30) command. I seem to recall that on a sun3 this the AKCL code and xlispstat code run at about the same speed. I have not yet confirmed this. If so, then the relative performance of the AKCL version to xlispstat may be quite hardware-dependent. The Allegro version on a DEC 5000 is considerably slower and larger than the AKCL version, but I have not yet figured out how to tune Allegro's memory management. The Macintosh CL version seems to run at least as fast as xlispstat on the Macintosh. To port this code to another CL, you need to Edit defsys.lsp to add any necessary definitions Add a top level to lstoplevel.lsp (this is only needed if you want to recover the history mechanism, which is broken by shadowing *, etc.) Write versions of the lisp and/or C glue files to interface to the C code in lib. Experiment with tuning the memory management to run reasonably in statistical applications. If you do port this code to another CL, please let me know so I can add it to this distribution.
