I'd like to invite comments on a new/proposed module: Math::Gauss.
This module started with my need for an implementation of the the inverse of the Gaussian distribution function - which is occasionally required (for instance to create QQ and probability plots) but which can be hard to find. (I could not find an implementation on CPAN.) At which point, it was easy enough to throw in an implementation of the actual Gaussian distribution function, as well as a short-hand for the actual probability density (including all the required normalization factors) to make a self-contained, handy package.
The design of this module was guided by a few simple principles:
- Simple, straightforward interface
- Pure Perl implementation for portability
- Includes the inverse CDF
- Good-enough accuracy, in return for simple, non-iterative implementations
A current version of this module is here:
Download.
Feel free to take a look and let me know what you think, in particular:
- Is this useful?
- Is anything missing?
- Is the name well-chosen?
Thanks!
