[Help-gsl] Question regarding GSL histogram PDF

[Bas Jansen]

Dear All,

I am trying to implement a KS test on 2 Histogram PDFs that I have and i 
am trying to calculate the maximum distance between the two 
distributions now but I seem to be failing with getting the actual sum 
in a given bin.

I assumed (based on the documentation) that I should be able to retrieve 
the sum by using ((my_type)->pdf->sum+x) where x is the bin that i want 
but apparently that's not how it should be done.

Could anyone possible clarify how it should be addressed?

Thanks in advance,
Bas Jansen

PS: I added a tiny piece of my code as an example, right now it just is 
supposed to print the value before i do the actual test.

   float D;
   for (i = 0; i < chrom->hits-1; i++) {
       for (j = i+1; j < chrom->hits; j++) {
           D = 0;
           printf("%f\n",(((chrom+i)->pdf)->sum+2));
           /* Do stuff */
       }
   }
