Fallout 1's random number generator

[Sduibek]

Does anyone know how this works? From the debug log we can see seomthing like:

Chi squared is 18.597500, P = 36.420000 at 0.05
Sequence IS random, 95% confidence.

Of course sometimes you'll get "Warning! Sequence is NOT random!", but I have no idea what Chi and P are, so i've also no idea how to 'fix' it.

Thoughts?
