| The **Combined Tool** by the [[https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWG/HiggsCombination|Higgs Combination Group]] provides the ''combine'' command which runs different statistical methods with RooStats for some input, e.g. a text file (datacard) containing information on the systematic uncertainties, data and processes, [[limits:limits#Simple example: Running the combine tool|like the example below]]. It is extensively discussed here: | The **Combined Tool** by the [[https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWG/HiggsCombination|Higgs Combination Group]] provides the ''combine'' command which runs different statistical methods with RooStats for some input, e.g. a text file (datacard) containing information on the systematic uncertainties, data and processes, [[limits:limits#Simple example: Running the combine tool|like the example below]].

| To make a Brazilian plot, you can make a simple python script that automatically creates the datacards for different values of some parameter like the invariant mass. [[limits:brazilianplotexample|This example]] shows scan for the background uncertainty. | To make a Brazilian plot, you can make a simple python script that automatically creates the datacards for different values of some parameter like the invariant mass.
