// Create a Gaussian PDF using the Workspace Factory (this is essentially the shorthand for creating a Gaussian). RooWorkspace* myWorkspace = new RooWorkspace("myWorkspace"); myWorkspace->factory("Gaussian::g(x[-5, 5], mu[0], sigma[1]");

Example code: What's in the workspace?


// Open the appropriate ROOT file.
root -l myFile.root
// Import the workspace.
myWorkspace = (RooWorkspace*) _file0->Get("myWorkspace");
// Print the workspace contents.
myWorkspace.Print();

Example code: accessing the workspace


// Open the appropriate ROOT file.
root -l BR5_MSSM_signal90_combined_datastat_model.root
// Import the workspace.
myWorkspace = (RooWorkspace*) _file0->Get("combined");
// Print the workspace contents.
myWorkspace->Print();
// Import the PDF.
RooAbsPdf* myPDF = myWorkspace->pdf("model_BR5_MSSM_signal90");
// Import the variable for the observable.
RooRealVar* myObservable = myWorkspace->var("obs");
// Create a RooPlot frame using the imported variable..
RooPlot* myFrame = myObservable.frame();
// Plot the PDF on the created RooPlot frame.
myPDF.plotOn(myFrame);
// Draw the RooPlot.
myFrame->Draw();

RooStats

RooStats provides tools for high-level statistics questions in ROOT. It builds on RooFit, which provides basic building blocks for statistical questions.
