|Statistical (and other)
Packages Available as Free Software
click here to return to
social change page
This page lists primarily statistical software, along with mapping,
spreadsheets, database, stuff to do data analysis or
management. All of the packages are free to use, that
is: there is no charge for individuals to use them. Many of the
websites say that individuals are free to download and use the
packages. In some cases, there may be charges to institutions. Some
of the packages are also open, that is, they are free to use and
the source code is freely available so anyone can make modifications
to the programs if they wish to. At the bottom of this page, I
list a few sites that have information about what "free" means.
Please note: I've only used a few of these software
programs a little bit, so I can't say much about how good they
are, whether they crash, have viruses, or much else about
them. If you use them, please let me know how well they
work. If there are any major problems, I'll take them off
this list. I'm sorry to add the usual disclaimer that, while
I don't expect any problems with them, if you use any of these, I
can't be responsible for any problems that may occur. Also, I'm
not necessarily recommending any, just providing info and links.
There are many free statistical programs. See this
at Citizendium about free statistical software.
Also see here http://gsociology.icaap.org/methods/softsum.html
for a brief summary of some of the programs.
Several of these stat programs were
reviewed in an article in Opus 12, a journal covering Opus
12 Foundation research. Stawicki SPA. Guide to free statistical
software: General applications. OPUS 12 Scientist
Reviewed OpenStat, Sofa, PSPP, MicrOsiris and a few others. Just
describes the programs.
looked at R and mentioned a few others (OpenStat and MicroOsiris).
"Free Statistics Software, Yours, Free to keep...."
Felix Grant, Scientific Computing World, Sept/Oct 2004,
This isn't a review of the packages, but a look at which ones
are popular http://r4stats.com/articles/popularity/
The Popularity of Data Analysis Software, by Robert A. Muenchen
Also look at this, the most popular response, http://www.researchgate.net/post/What_is_the_most_commonly_used_statistical_analysis_software_in_the_world
by Robert Thomas Brennan · Harvard University, explaining some of
the difficulties in answering which is the most popular. For
example, excel has a lot of statistical functions, but isn't thought
of as statistical software so may not be counted
I also compared 8 programs
(LazStat, easyreg, epidata, WinIDAMS, instat, MicrOsiris, Epi Info and PSPP), and
added excel and Gnumeric,
data sets have no missing values, shown here http://gsociology.icaap.org/methods/comparing_freestaprograms.html
Basically, for correlation and simple regression, all gave the same
or similar results. Some also had the same results for forward
I also compared 6 programs (MicrOsiris Epi Info, WinIDAMS, Instat,
PSPP, JASP), when data sets do have missing values,
handle missing data with my data sets. WinIDAMS isn't so easy but
after a lot of tries and emails with UNESCO staff, I understood it
well enough to get it to work.

Stata and JAGS"
"a data-entry and data-checking program for Microsoft

to the website, "EpiData Analysis performs basic statistical
analysis, graphs, and comprehensive data management. E.g.
descriptive statistics, SPC Charts, Recoding data, label values and
variables. Defining missing values."

diagramming software, and SampleXS, which is a sample size
calculator, which allows for design effects. The help box has
very good documentation about sampling and what the program
does. For social surveyors, you need to change the confidence
interval to 5 rather than .5. However, the site doesn't have
any information about the people who developed this.

Free statistical program, from Bill Miller. According
to Mr. Miller, "LazStats is written in a free Pascal compiler
(Lazarus) that can be downloaded for free and is compatible to the
former Borland compiler Delphi. I've made the source of
LazStats available so it can be compiled for other systems such as
Apple or Linux platforms. It contains features very similar to
OpenStat and any programmer can add their own routines if they
want." OpenStat is another program on this website. The 2014
version has a kind of problem, that the pairwise deletion for
correlations does not work. OpenStat does listwise deletion instead,
even if you specify pairwise. LazStat works, though.
