This month, you can read about some data analysis software in The American Statistician and in Behavior Research Methods, Instruments, and Computers This is public domain software written while I was at UCSD. For various legal reasons, it is distributed at the cost of a magnetic tape and mailing. I know of about 200 sites using the programs, and I occasionally take some time out to announce the package's availability to the net. The programs are available on a USENIX tape of a few years ago, but the current distribution has a few system dependent incompatibilities removed (e.g., the programs run on System V (TM) on 3B (TM) processors). A lot more detail follows, and you can always call or write.

The programs are designed with the UNIX System philosophy that individual programs should be designed as tools that do one task well and produce output suitable for input via pipes to other programs. Interactive use is supported in the UNIX System shell which also provides 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 Functionality often built into statistical packages (e.g., graphics, sorting and other data manipulation) is not re-invented in UNIX|STAT which delegates such responsibility to standard UNIX System tools. FEATURES easy to use (negligible training period) simple input formats (free format field oriented) used in pipelines with other UNIX System utilities (sort, vi) flexible data manipulation data validation provided (range and type checking) full documentation support (manual entries, tutorials) extensible (many modular C functions) faster than most packages (usually < second/analysis) small enough for micros (10-25K byte programs) runs on any UNIX System (V6, V7, 2.8BSD, 4BSD, III.0, 5.0, others) public domain software in use at > 200 UNIX System sites for three years DATA TRANSFORMATION PROGRAMS abut abut data files dm column oriented data manipulator io control and monitor input and output maketrix create matrix type file from free-form file perm randomly permute lines in a file repeat repeat a pattern or file reverse reverse lines and characters series print a series of numbers transpose transpose matrix type file ANALYSIS PROGRAMS anova multi-factor anova (repeated measures & unequal cells) calc interactive algebraic modeling calculator critf critical F-ratio given probability and degrees of freedom desc descriptive statistics, histograms, frequency tables dprime signal detection d' and beta calculations pair paired data statistics, linear regression, scatterplots pof probability of F-ratio given degrees of freedom regress multivariate linear regression ts time series analysis and plots validata verify data file consistency vincent time-series comparison UNIX|STAT is Public Domain The programs have been released to the public and are distributed to anyone who wants them. Persons wanting to get a copy of the package should contact me directly. A distribution fee is charged to cover my costs ($20.00 U.S.), except for AT&T locations for which there is no cost to me. Documentation for the package is available free of charge. Please contact Gary Perlman for information about tape formats if tar 1600 bpi format is not useful. The distribution includes a magnetic tape with: The C source files for all the programs. The documentation source files. A collection of test examples.
