Ok let's approach this one step at a time starting with improper
integration because tests for AQ depend on it.
What are the modifications to the class Infinite in Math-995 that are:
1: necessary
2: desirable
for acceptance to commons?
what bits of code can be reused from existing ones in commons

I have two issues with the above:
1: Cant imagine how someone would use AQ. Which means as Gilles noticed,
you can't focus on the hard to converge sections of the integral.
2: If you use the integration without AQ. Any funct
The math is quite simple.
What is not clear is what the numerical properties are for substitution of
the sort being advocated.
Which functions will do better with substitution? Which will do better
with Laguerre polynomials?

Without AQ, you have the achilles heel with high frequency functions that
Gilles acknowledged in his comments. So, how do you propose to do AQ with
Gauss-Hermite?
I guess I don't know what you mean by "numerical analysis".

Asymptotically, the 2-sample D_n,m test statistic (see [1]) has a
K-S distribution, so for large samples just using the cdf we already
have is appropriate. For small

The method is described here:
http://en.wikipedia.org/wiki/Integration_by_substitution
My patch uses it for improper integration via the change of variable
t/(1-t^2) as suggested in :
http://en.wikipedia.org/wiki/Numerical_integration
Please reach back if anyone understands this concept.

1. Konstantin just showed with a link that other packages use the change of

2 The theoretical argument for the change of variables method is documented
on Wikipedia. It is such a standard way that it is on wikipedia. I did
another search on google. Here is another wikipedia link:

Phil,
I feel that you are blocking/delaying the use of improper integration to
commons users with your objection that you don't understand all the
alternatives.
