Chi2AsymmetricErrorFitStatistic#
- class gammapy.stats.Chi2AsymmetricErrorFitStatistic[source]#
Bases:
FitStatisticPseudo-Chi2 fit statistic class for measurements with gaussian asymmetric errors with upper limits.
Assumes that regular data follow asymmetric normal pdf and upper limits follow complementary error functions.
Methods Summary
stat_array_dataset(dataset)Estimate statistic from probability distributions, assumes that flux points correspond to asymmetric gaussians and upper limits complementary error functions.
