Classes

class  Chi2Metric
 Implementation of the standard $ \chi^2 $ metric derived from maximum likelihood with Gaussian uncertainties. With default L2 norm corresponds to the formula. More...
 
class  LogMetric
 Implementation of the standard $ \chi^2 $ metric with intensity $I$ and experimental data $D$ being replaced by $ \log_{10} I $ and $\log_{10} D$ accordingly. With default L2 norm corresponds to the formula. More...
 
class  meanRelativeDifferenceMetric
 Implementation of relative difference metric. With default L2 norm and weighting off corresponds to the formula. More...
 
class  ObjectiveMetric
 Base class for metric implementations. More...
 
class  PoissonLikeMetric
 Implementation of $ \chi^2 $ metric with standard deviation $\sigma = max(\sqrt{I}, 1)$, where $I$ is the simulated intensity. With default L2 norm corresponds to the formula. More...
 
class  RQ4Metric
 Implementation of relative difference metric. With default L2 norm and weighting off corresponds to the formula. More...
