Error of kurtosis and skew

Hi ROOTusers,

Could anyone help me, how to get error of Kurtosis and skewness of a histogram ?

like for error of mean we use


for kurtosis and skewness
there is GetKurtosis(), GetSkewness().

there is no option to get error of it .

Is there any way to Get these ?

Thank you


you can get the errors on the kurtosis and the skewness on the x axis by calling

see … etSkewness

However, the value of skewness and kurtosis (in contrast to the standard deviation) are computed using the bin centers. The values obtained could be then biased by a value which is not taken into account in these formulas.

Best Regards
