Re: Stats: Testing whether data is normally (Gaussian) distributed

[lin0]

Hi andye

I do not know any CPAN module that implements a normality test. However, if you decided to write your own, you could try implementing the Person's Chi square test. One way of implementing this test could be by combining the Statistics::ChiSquare module with the Statistics::Distributions module.

Good luck!

Currently the ChiSquare module assumes that the data you're testing is meant to be evenly distributed. I've wanted to make that configurable for a long time, so if anyone can come up with a nice way of doing it, I would be delighted to apply your patch.

I also need to hack on it to support more degrees of freedom.
