## Detailed Description

Implementing the Barlow-Beeston method for taking into account the statistical uncertainty of a Monte-Carlo fit template.

import ROOT
# First, construct a likelihood model with a Gaussian signal on top of a uniform background
x = ROOT.RooRealVar("x", "x", -20, 20)
x.setBins(25)
meanG = ROOT.RooRealVar("meanG", "meanG", 1, -10, 10)
sigG = ROOT.RooRealVar("sigG", "sigG", 1.5, -10, 10)
g = ROOT.RooGaussian("g", "Gauss", x, meanG, sigG)
u = ROOT.RooUniform("u", "Uniform", x)
# Generate the data to be fitted
sigData = g.generate(x, 50)
bkgData = u.generate(x, 1000)
sumData = ROOT.RooDataSet("sumData", "Gauss + Uniform", x)
sumData.append(sigData)
sumData.append(bkgData)
# Make histogram templates for signal and background.
# Let's take a signal distribution with low statistics and a more accurate
# background distribution.
# Normally, these come from Monte Carlo simulations, but we will just generate them.
dh_sig = g.generateBinned(x, 50)
dh_bkg = u.generateBinned(x, 10000)
# Case 0 - 'Rigid templates'
# Construct histogram shapes for signal and background
p_h_sig = ROOT.RooHistFunc("p_h_sig", "p_h_sig", x, dh_sig)
p_h_bkg = ROOT.RooHistFunc("p_h_bkg", "p_h_bkg", x, dh_bkg)
# Construct scale factors for adding the two distributions
Asig0 = ROOT.RooRealVar("Asig", "Asig", 1, 0.01, 5000)

# Construct the sum model
model0 = ROOT.RooRealSumPdf("model0", "model0", [p_h_sig, p_h_bkg], [Asig0, Abkg0], True)
# Case 1 - 'Barlow Beeston'
# Construct parameterized histogram shapes for signal and background
p_ph_sig1 = ROOT.RooParamHistFunc("p_ph_sig", "p_ph_sig", dh_sig, x)
p_ph_bkg1 = ROOT.RooParamHistFunc("p_ph_bkg", "p_ph_bkg", dh_bkg, x)

# Construct the sum of these
model_tmp = ROOT.RooRealSumPdf("sp_ph", "sp_ph", [p_ph_sig1, p_ph_bkg1], [Asig1, Abkg1], True)
# Construct the subsidiary poisson measurements constraining the histogram parameters
# These ensure that the bin contents of the histograms are only allowed to vary within
# the statistical uncertainty of the Monte Carlo.
hc_sig = ROOT.RooHistConstraint("hc_sig", "hc_sig", p_ph_sig1)
hc_bkg = ROOT.RooHistConstraint("hc_bkg", "hc_bkg", p_ph_bkg1)
# Construct the joint model with template PDFs and constraints
model1 = ROOT.RooProdPdf("model1", "model1", {hc_sig, hc_bkg}, Conditional=(model_tmp, x))
# Case 2 - 'Barlow Beeston' light (one parameter per bin for all samples)
# Construct the histogram shapes, using the same parameters for signal and background
# This requires passing the first histogram to the second, so that their common parameters
# can be re-used.
# The first ParamHistFunc will create one parameter per bin, such as p_ph_sig2_gamma_bin_0.
# This allows bin 0 to fluctuate up and down.
# Then, the SAME parameters are connected to the background histogram, so the bins fluctuate
# synchronously. This reduces the number of parameters.
p_ph_sig2 = ROOT.RooParamHistFunc("p_ph_sig2", "p_ph_sig2", dh_sig, x)

Abkg2 = ROOT.RooRealVar("Abkg", "Abkg", 1, 0.01, 5000)
# As before, construct the sum of signal2 and background2
model2_tmp = ROOT.RooRealSumPdf("sp_ph", "sp_ph", [p_ph_sig2, p_ph_bkg2], [Asig2, Abkg2], True)
# Construct the subsidiary poisson measurements constraining the statistical fluctuations
