I intended the core.matrix.stats to be used as a lightweight library as
for statistical functions of this nature, while remaining compatible with
Incanter and core.matrix. I agree something more lightweight than the whole
of Incanter is often required.
Thanks Mike,
This looks very much like what I want, in principle, although in practice I'm
interested in functions like t-test and chisq-test, which haven't yet made it
into core.matrix.stats as far as I can see.
FWIW I'd be wary about just copying those things from Incanter, at least
It may require conversion to/from Java arrays to use them, but there are
Apache Commons Math implementations of the computations you mention, and
many others:
http://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/stat/inference/ChiSquareTest.html
Does anyone know of a simple/minimal Clojure library, or just a chunk of
Clojure source code that I could cut/paste, that implements basic statistical
tests like t-tests and chi-squared tests? I don't want to use incanter but I'd
also rather not write this stuff from scratch.
Thanks,
-Lee
One option would be to call R from Clojure. I haven't tried this, and I
don't know how well it would fit your needs.
Rincanter
http://joelboehland.com/posts/all-your-datasets-r-belong-to-us.html is
supposed to allow this. Presumably it would bypass the Incanter functions
that you don't
Thanks so much Marshall.
Adding -Djava.awt.headless=true to my :jvm-opts does indeed fix the
additional java process problem, so that's helpful if I don't find an
alternative to incanter.
The R options are interesting but probably not a good solution in my case; I'll
be calling these tests
