Hi HS

❝ I get 77.62276% (N=n1+n2=32) in [image]. Fartsie on my machine: 77.6228% and StudySize 77.607% (120000 Monte Carlo Simulations: 77.81% after 9 seconds on a double Xeon 2.8GHz machine).


Good, seems I have good agreement with your software, I am happy to see that.

❝ How did you set limits for the Danish requirements?


I am not sure I understand what you mean when asking how I set the limits for the Danish reqs. I evaluate BE, then I use a further requirement which goes like this: If upper bound < 1.0 then it is a failure, and if lower bound > then also fail.
In C lingo:
if (FailWhen1NotPartOfCI)
         {
             if (exp(LogLo)>1.0) OK=0;
             if (exp(LogHi)<1.0) OK=0;                   
         }

Where OK is just my private own little boolean (actually in C it is an int, but that's another story) to indicate if a dataset if accepted or rejected. But right now I have a feeling this is not really what you meant?


Best regards.
EM

PS: If there are some geekolophystic souls out there to whom it looks like my code has not been optimised for speed (or who would like to tell me log(1)=0) then yes, you are right, there's still work to be done :-D
