Preparing Data For Statistical Analysis and Reporting

Ruby

How much data munging is done by Ruby-ists?

If you need some tools for preparing data for analysis, transforming
data, and cleaning data up, there are some tools to check out at:

http://directory.fsf.org/math/stats

including:

Vilno
DAP
PSPP

DAP is an open-source version of SAS
PSPP is an open-source version of SPSS
Vilno uses it’s own language for data transformation, similar to SQL
SELECT, SAS, and SPSS.

For statistics itself, I am rather curious about Apophenia
( apparently a C library for statistics that can be called by any
statistics package).

Thanks for the pointers! This is actually something I do a lot in my day
job. Most of the data extraction is done in Perl, mostly because Ruby
didn’t exist when I wrote most of the code. If there were a couple other
Ruby programmers around, I’d port it to Ruby/Rails/Ruport.

Nearly all of the statistics I do is in R, also an open source project.
There is an R-Ruby bridge called “RSRuby”, so that would be another way
to get into this.

Nearly everything I do these days is large enough that I use either SQL
Server or PostgreSQL to manage the datasets. By the end of the year I
expect it will all be in PostgreSQL – the SQL Server licenses are too
expensive.
