Feature Request - Stdev, and statistical functions, and data sets or tables.
Issue #317
closed
Originally reported on Google Code with ID 317
What steps will reproduce the problem?
1. I wanted to calculate the standard deviation of a series of numbers.
2. I searched for it but there was no Stdev function in the functions list.
What is the expected output? What do you see instead?
I'd like to calculate StdDev( [set] ). I think maybe it should be possible
to define a set of values maybe by typing X = (1,1.1,1.8,0.8,0.7)
and then StdDev(X), or else typing Stdev(1,1.1,1.8,0.8,0.7).
What version of the product are you using? On what operating system?
0.10.1 on ubuntu (9.04)
Please provide any additional information below.
Statistical functions, and data-sets that are fed to them, are particularly
useful in sciences. Analytical chemistry, etc.
While I'm waxing feature-requesty, may I also say that it would be cool to
define your own functions, via a simple scripting language, that could be
plugged in. Maybe using LUA or Python, which are easy to embed in any
C/C++ app. You could even use it to do your evaluations. I currently use
Python's interactive interpreter instead of a calculator app, because it
has all the functions I need, it just doesn't have a pretty interface like
Speedcrunch.

``` Added 'stddev', 'variance' and 'absdev' on a branch: https://gitorious.org/~enrico/speedcrunch/enricos-speedcrunch/commit/593acb707e9e9dfc08e83b73a167919f1e8e54e8
When that is merged to master, this request can be closed.
