Hello everyone,
I’d like to smear one observable while generating toys from a pdf.
I tried to follow the example from the roofit tutorial ( https://root.cern.ch/root/html/tutorials/roofit/rf801_mcstudy.C.html ). RooRandomizeParamMCSModule::sampleUniform works fine, but whenever I try to use sampleGaussian instead, I get a seg violation.
This is the small dummy script I try to run:
import ROOT as r
import RooFit as rf
# My dummy variable
x = r.RooRealVar( 'x', 'x', 0., 10.)
# Construct dummy model
mean = r.RooRealVar( 'mean', 'mean', -1., 1. )
sigma = r.RooRealVar( 'sigma', 'sigma', .1, .2 )
gauss = r.RooGaussian( 'gauss', 'gauss', x, mean, sigma )
nsig = r.RooRealVar( 'nsig', 'nsig', 0., 10000. )
model = r.RooExtendPdf( 'model', 'model', gauss, nsig )
# Create manager
mc_study = r.RooMCStudy( model, r.RooArgSet(x), rf.Binned(r.kTRUE), rf.Silence(), rf.Extended(), rf.FitOptions( rf.Save(r.kTRUE), rf.PrintEvalErrors(0) ) )
# Smear x
randModule = r.RooRandomizeParamMCSModule()
randModule.sampleGaussian( x, 0., 1.)
mc_study.addModule(randModule)
# Generate and fit toys
mc_study.generateAndFit(10, 1000)
I get the following error:
*** Break *** segmentation violation
