Get Error of total yield from histo

Hello

Is there a fast way (except adding the bin errors in quadrature) to get the error on the total sum of weights , i.e, analogous to h1.GetSumOfWeights() is there a way to h1.GetTotalError() ?

I hope my question makes sense.

TIA
Alex

See TH1::GetStats(stats)

stats[1] is the total sum of weight square.
