Anderson-Darling test with a user-defined function

Hello everyone,

After looking at the goftest.C, I have a small question regarding the possibility to run the Anderson-Darling test with a user defined function TF1.

If I have a TF1 function defined as such:

TF1 *f1 = new TF1("f1","function expression",-10,10);

Can I simply use the following:

ROOT::Math::GoFTest* test = new ROOT::Math::GoFTest(nEvents, dist,*f1);

where dist is an array containing the distribution I am running the AD test on?

I have tried to run this with some example but the results are a bit strange so I was wondering if I was missing something…

Thanks in advance :slight_smile:
