When fitting to data with low statistics and near physical boundaries, extra measures need to be taken to ensure proper statistical coverage. The method NOvA uses is called the Feldman-Cousins procedure, which entails fitting thousands of independent pseudoexperiments to generate acceptance intervals that are then used to correct our fits. The scale required by the Feldman-Cousins procedure makes it extremely computationally intensive. In past analyses, it has taken up to several weeks to complete, bottlenecking our final results. We will present recent work by members of the NOA experiment and the SciDAC4 collaboration that utilized the super-computing facilities at NERSC to process our Feldman-Cousins corrections over 50x faster, allowing us to perform a greater number of studies while increasing the precision of our fits.
