Dear ROOTers,
TH2 class has these member functions:
->GetRMS
->GetRMSError
->GetCovariance
->GetCorrelationFactor
(of course, GetCovariance and GetRMSError would be sufficient to get all the rest of the info),
however, I haven’t found how to get info for (the equivalents of non-existent)
->GetCorrelationFactorError(1,2)
and/or
->GetCovarianceError(1,2)
as there are no such member functions.
Is there a way to do this in ROOT (I know how to do this by hand, of course)?
If there is currently no such functionality in ROOT, in my opinion,
it would be a very useful addition (so one can estimate how
significant a seemingly non-zero correlation between two variables
in a particular set of data points might actually be).
could experts please comment on this or/and help?
thanks!
Vladimir
