Error on higher moments?

ROOT

Hello,
Is there a way, with ROOT, to estimate the error on higher moments of a distribution (Kurtosis and Skewness) ?

Thank you

See TH1::GetSkewness and TH1::GetKurtosis
These functions were introduced in version 4.04/02

Yes, these functions allow to compute the Kurtosis and the Skewness, but not the error on those values.

It is always helpfull to know the error on the computed values.

In the development version in CVS, we have added the computation of the errors on all the moments. see
root.cern.ch/root/htmldoc/TH1.html#TH1:GetMean
root.cern.ch/root/htmldoc/TH1.html#TH1:GetRMS
root.cern.ch/root/htmldoc/TH1.ht … etSkewness
root.cern.ch/root/htmldoc/TH1.ht … etKurtosis
