FREE STATISTICAL SOFTWARE
Amazing. All statistics can be done with free software - easily downloaded if you know where to get
what. You don't get all statistical procedures in any single free program. You've
to install a few programs to suit your own needs.
A word about freeware: What's dished out by Search Engines, as freeware is not always really free, there's
usually a catch somewhere. So, tested lists like mine are useful. Remember also
what's free today may not be so tomorrow. Such is life!
The download links tell you all about the programs.
EpiInfo is a huge program designed for epidemiologists; has most
statistical subroutines. With Epi Info, "epidemiologists, public
health and medical professionals and statisticians can rapidly develop a
questionnaire or form, customize the data entry process, and enter and analyze
data. All statistics, tables, graphs, and maps are produced with simple
commands". That's what it promises.
OpenStat is small in size, a very nice and
comprehensive package. Has practically everything statisticians look for in a
program for everyday use. Recommended especially for irregular stat users.
SSP Smith's Statistical Package is a very
user-friendly statistics program. If you're calculating means, variances,
correlations and working out routine regressions.
Instat is another big program. Has just about
everything. Write to them if it's missing this or that.
is freely distributed by the UNESCO. Truly free and serves many purposes, like everything the UN
does for underdeveloped souls.
GragProg A nice program for all
manner of X-Y graphing, comes with a a calculator as a bonus.
Graph is a similar, even
MEX Math expression calculator. Handy for
numerical calculations involving common functions such as powers of x, exp(.),
log(.) and the trigonometric ones as well.
StatCalc gives probabilities for several
continuous and discrete distributions; useful as well for getting inverses for
given probabilities. Get this, and never look up again those tattered books in
the library for significance tests.
StaTable is another program that gives you all
the percentage points, and more. A different format, but a very good one.
Deadline is a wonderful tool for
solving algebraic equations, graphing and evaluating them. Most impressive. Say
'Ah', after looking at some pictures of equations you like best. But you must
set the 'range', the focus and scope, so to speak.
Convert is an easy to use unit conversion
program that will " convert the most popular units of distance,
temperature, volume, time, speed, mass, power, density, pressure, energy and
many others, including the ability to create custom conversions.
