There are a few reviews of free statistical software. The author of Microsiris also has also contributed or co-contributed several components to WinIdams. While Microsiris doesn't appear to be used in academic research, the author of the program was one of the original authors of OSIRIS, which was the starting program from which WinIdams was developed. Irristat is used in an agricultural report, EasyReg is listed or used in several papers, EpiInfo was also used in several papers, R was used in a number of papers and WinIdams was used in other papers. For example, OpenStat was used in a research letter to JAMA and in several published studies.

These free software packages have been used in a number of scholarly publications. Several of the packages, PSPP, R and Osiris don't appear to give any statements about why they were developed, other than just general use for statistical analysis. Examples are Irristat, developed for agricultural analysis, and Epi Info, developed for public health. Other packages were developed for specific purposes but can be more generally used. OpenStat and Instat were developed as teaching aids.

Īt least one package, WinIDAMS, was developed for the purposes of making key technologies available to those who could not otherwise afford them, to empower development.

Some of these software packages from individuals include Easyreg, MicrOsiris, OpenStat, PSPP, SOFA, and Zelig. These packages are notable in that it is not just open source but also free software in the same sense that material written on Wikipedia is free: others can edit, use, and redistribute at will.Ī large proportion of free statistical software packages, however, are from individuals.

Some packages are developed for specific purposes (e.g., time series analysis, factor analysis, calculators for probability distributions, etc.), while others are general packages, with a variety of statistical procedures. These packages come from a variety of sources, including governments, nongovernmental organizations (NGOs) like UNESCO, and universities, and are also developed by individuals. In general, free statistical software gives results that are the same as the results from commercial programs, and many of the packages are fairly easy to learn, using menu systems, although a few are command-driven. Just a few of the software packages mentioned here are also free as in the sense of free speech: they are not only open source but also free software in the sense that the source code of the software is freely available and can be freely modified by anyone who so desires, and also distributed to others, as long as those re-distributed modifications remain free in exactly the same strong sense.įree statistical software is a practical alternative to commercial packages.
