|STAT Home Page

|STAT is a set of about 30 data manipulation and analysis programs developed by Gary Perlman at the University of California, San Diego and at the Wang Institute. The manipulation programs are general utilities that work with other standard programs like sort. The analysis programs compute most widely used statistics. |STAT programs are designed with the philosophy that individual programs should be designed as tools that do one task well and produce output suitable for input via pipes to |STAT and other programs. Interactive use is supported in the command line interpreter/editor while batch files or shell scripts provide a programming language for complex analyses. Typical usage involves a pipeline of transformations of data followed by input to an analysis program, summarized schematically by:
INPUT DATA | TRANSFORM | ANALYSIS | OUTPUT RESULTS

Obtaining |STAT

Instructions updated: 2001-05-12

|STAT is no longer available via e-mail or FTP. It is now stored at an unadvertized Web address. The file: stat.tar.Z is compressed, tar archive of the package. To unpack the archive, you need uncompress or zcat, and tar. To ensure that the distribution restrictions on |STAT are maintained, you must request the location of the file from perlman@acm.org with a message containing:

   I AGREE TO ADHERE TO THE CONDITIONS OF USING |STAT.
   I AGREE NOT TO SHARE THE |STAT LOCATION WITH OTHERS.
Please include a subject with |STAT in it or the spam filters may not let your request through.

After obtaining the file you should run the following commands:

   uncompress stat.tar.Z  # to create stat.tar
   tar xvf stat.tar       # to extract the files
You should then have a stat directory that will take up about a megabyte. In the stat/src directory, you should make any necessary changes to the makefile and then run make to build the package. Installation notes are available. In addition to the online manuals, the file handbook.html contains an HTML version of the |STAT handbook, which is also available in PDF format.

DOS Version of |STAT

The compiled DOS version of |STAT (with documentation) is available in a WinZip archive. No permission or password is needed to access the DOS version, but a note informing perlman@acm.org would be appreciated.

Distribution Conditions

CAREFULLY READ THE FOLLOWING CONDITIONS. IF YOU DO NOT FIND THEM ACCEPTABLE, YOU SHOULD NOT USE |STAT.

|STAT IS PROVIDED "AS IS," WITHOUT ANY EXPRESS OR IMPLIED WARRANTY. THE USER ASSUMES ALL RISKS OF USING |STAT. THERE IS NO CLAIM OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. |STAT MAY NOT BE SUITED TO YOUR NEEDS. |STAT MAY NOT RUN ON YOUR PARTICULAR HARDWARE OR SOFTWARE CONFIGURATION. THE AVAILABILITY OF AND PROGRAMS IN |STAT MAY CHANGE WITHOUT NOTICE. NEITHER MANUFACTURER NOR DISTRIBUTOR BEAR RESPONSIBILITY FOR ANY MISHAP OR ECONOMIC LOSS RESULTING THEREFROM OF THE USE OF |STAT EVEN IF THE PROGRAMS PROVE TO BE DEFECTIVE. |STAT IS NOT INTENDED FOR CONSUMER USE.

CASUAL USE BY USERS NOT TRAINED IN STATISTICS, OR BY USERS NOT SUPERVISED BY PERSONS TRAINED IN STATISTICS, MUST BE AVOIDED. USERS MUST BE TRAINED AT THEIR OWN EXPENSE TO LEARN TO USE THE PROGRAMS. DATA ANALYSIS PROGRAMS MAKE MANY ASSUMPTIONS ABOUT DATA, THESE ASSUMPTIONS AFFECT THE VALIDITY OF CONCLUSIONS MADE BASED ON THE PROGRAMS. REFERENCES TO SOME APPROPRIATE STATISTICAL SOURCES ARE MADE IN THE |STAT HANDBOOK AND IN THE MANUAL ENTRIES FOR SPECIFIC PROGRAMS. |STAT PROGRAMS HAVE NOT BEEN VALIDATED FOR LARGE DATASETS, HIGHLY VARIABLE DATA, NOR VERY LARGE NUMBERS.

You may make copies of any tangible forms of |STAT programs, provided that there is no material gain involved, and provided that the information in this notice accompanies every copy. You may not copy printed documentation unless such duplication is for non- profit educational purposes. You may not provide |STAT as an inducement to buy your software or hardware or any products or services. You may distribute copies of |STAT, provided that mass distribution (such as electronic bulletin boards or anonymous ftp) is not used. You may not modify the source code for any purposes other than getting the programs to work on your system. Any costs in compiling or porting |STAT to your system are your's alone, and not any other parties. You may not distribute any modified source code or documentation to users at any sites other than your own.

All rights reserved. No part of this handbook may be reproduced or transmitted in any form or by any means without prior written permission from the author. Non-profit organizations may make copies provided such copies are not made for resale.
