I am trying to generate from a 3D pdf:
datagen = corr_RD.generate(RooArgSet(Ep,Eg,costheg),numevents);
I find strange steps in the correlations of the generated variables e.g.
Does anybody knows why this happens?
The output of generation says:
[#1] INFO:NumericIntegration – RooRealIntegral::init(corr_RD_Int[Eg,Ep,costheg]) using numeric integrator RooAdaptiveIntegratorND to calculate Int(Ep,Eg,costheg)
[#0] WARNING:NumericIntegration – RooAdaptiveIntegratorND::dtor(corr_RD) WARNING: Number of suppressed warningings about integral evaluations where target precision was not reached is 1
thanks in advance
