GetUncertainty() [1/2]

template<class DATA , class... BASES>

template<bool B = true, class = typename std::enable_if<B && HasBinUncertainty()>::type>

double ROOT::Experimental::Detail::RHistBinStat< DATA, BASES >::GetUncertainty ( ) const

inline

Calculate the bin content's uncertainty for the given bin, using base class information, i.e.

forwarding to a base's GetUncertaintyImpl().

Definition at line 491 of file RHistData.hxx.

GetUncertainty() [2/2]

template<class DATA , class... BASES>

template<bool B = true, class = typename std::enable_if<B && !HasBinUncertainty()>::type>

double ROOT::Experimental::Detail::RHistBinStat< DATA, BASES >::GetUncertainty (   ... ) const

inline

Calculate the bin content's uncertainty for the given bin, using Poisson statistics on the absolute bin content.

Only available if no base provides this functionality. Requires GetContent().
