This page lists primarily statistical software, along with mapping, spreadsheets, database, stuff to do data analysis or management. All of the packages are

**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 article http://en.citizendium.org/wiki/Free_statistical_software/Citable_Version 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 2010;4(1):12-13. http://journal.opus12.org/o12-ojs/ojs-2.1.1/index.php/o12sci/issue/view/86 Reviewed OpenStat, Sofa, PSPP, MicrOsiris and a few others. Just describes the programs.

Another review 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, http://www.scientific-computing.com/scwsepoct04free_statistics.html

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, when 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 stepwise.

I also compared 6 programs (MicrOsiris Epi Info, WinIDAMS, Instat, PSPP, JASP), when data sets do have missing values, shown here

http://gsociology.icaap.org/methods/comparing_freestaprograms_missing.html Basically, for correlation and simple regression all gave the same results. These are also the only programs that I can get to successfully and reliably 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.

Free Statistical Software

__Epi Info__

Epi Info is available
from http://wwwn.cdc.gov/epiinfo/

It is very large in size and will take considerable time to
download. This is a program for entering and analyzing data,
developed for epidemiologists, but can be used for basic
statistical analysis by anyone. This program is also not
easy to learn on your own, but see a couple of free on line
manuals:

This site also links to Introduction to Epi Info and other resources http://www.epiinformatics.com/

The North Carolina Center for Public Health Preparedness Training Website http://cphp.sph.unc.edu/training/index.php has free on line training classes for epi info.

CSPro (Census and Survey Processing System) http://www.census.gov/population/international/software/cspro/ a public-domain software package for entering, tabulating and mapping census and survey data.

R is a very widely used program, with tons of documentation

R: The Comprehensive R Archive Network http://cran.r-project.org/ "R, also known as "GNU S", is a language and environment for statistical computing and graphics." It is, I understand, like S+, a statistical language. R is better for graphics than SAS. However, R is complex, and takes a lot of study, so only use this if you have complex statistical or graphical needs. If this site doesn't work, try http://cran.us.r-project.org/ in the US, or http://www.stats.bris.ac.uk/R/ in the UK.

There are many graphical interfaces. Several are reviewed here http://decisionstats.com/2010/10/05/interfaces-to-r/ and this June 2012 issue of Journal of Statistical Software also reviews several of the GUIs http://www.jstatsoft.org/v49 and this page from linux.com http://www.linuxlinks.com/article/20110306113701179/GUIsforR.html Here is a poll on which GUIs are most used http://www.kdnuggets.com/polls/2011/r-gui-used.html (R Studio was the top, out of 562 votes). Here is a 2015 list of the "Best free GUIs for R" http://www.linuxlinks.com/article/20110306113701179/GUIsforR.html Just a few words about each one.

R Commander is described here
http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/

Easyreg http://econ.la.psu.edu/~hbierens/EASYREG.HTM from Herman J. Bierens. This is actually an econometrics program, but it apparently does basic statistics as well, and some very advanced statistics related to econometrics, including time series analysis.

Emacs Speaks Statistics (ESS) http://ess.r-project.org/ "is an add-on package for emacs text editors such as GNU Emacs and XEmacs. It is designed to support editing of scripts and interaction with various statistical analysis programs such as R, S-Plus, SAS, Stata and JAGS"

Epidata http://www.epidata.dk/ "a data-entry and data-checking program for Microsoft Windows." Epidata is data entry and data checking. According 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."

A related site is Pepi for windows at http://www.brixtonhealth.com/ - some statistical tests and descriptives. This site also includes a few other programs such as EpiGram, simple 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.

Instat is listed here http://www.reading.ac.uk/ssc/resourcepage/instat.php general statistical package. A few years ago, I used an old version to import an excel file. Correlations did okay when correlating two variables. When I last used this, the last case has to have values for all variables for Instat to completely read the data, at least for correlation.

JASP https://jasp-stats.org/ An alternative to SPSS and R. A fairly new package so still being developed. A lot of it seems Bayesian, but also the usual statistical tests.

Mentioned here: What Are the Odds? A Practical Guide to Computing and Reporting Bayes Factors http://docs.lib.purdue.edu/jps/vol7/iss1/2/

The JASP team wrote about it here http://www.psychologicalscience.org/index.php/publications/observer/2015/march-15/bayes-or-bust-with-new-softwares.html

Lazstat http://statprogramsplus.com/.index.html 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.

MicrOsiris http://www.microsiris.com/ from Neal and Susan Van Eck. This program "is derived from OSIRIS IV, a statistical and data management package developed and used at the University of Michigan and includes special techniques for data mining and analysis of nominal- and ordinal-scaled data. Its free but can contribute $25 to get rid of start up reminder screen.

PSPP http://www.gnu.org/software/pspp/ "is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions."

This page http://www.gnu.org/software/pspp/get.html lists where you can get it, in all the different versions (windows, unix, mac, etc)

For the windows version, get it here http://sourceforge.net/projects/pspp4windows/

and then click on the line that starts with ""Looking for the latest version? Download pspp ..." then lists a version number.

SalStat http://www.salstat.com/ general stat program, but you need to install python first. Also, no information about any of the people who made this.

SOFA - Statistics Open For All http://www.sofastatistics.com/home.php Currently being developed. From Dr Grant Paton-Simpson. Has some basic procedures, mean, median, sd, independent and paired t-tests, Mann-Whitney U, Wilcoxon Signed Ranks, Pearson's Chi Square, one-way ANOVAs, Kruskal Wallis H, and Spearman's and Pearson's correlations. As of 2/26/16, it does NOT have regression. Also, as of 2/26/16, the site talks about being installed on Windows 7, kinda old. No mention of 8 or 10. Can link directly to data from MySQL, SQLite, MS Access, and MS SQL Server, and can import data in csv or Excel format. Further information is here http://sourceforge.net/projects/sofastatistics/
