RooCustomizer is a factory class to produce clones of a prototype composite PDF object with the same structure but different leaf servers (parameters or dependents).

RooCustomizer supports two kinds of modifications:

replaceArg(leaf_arg, repl_arg): Replaces each occurence of leaf_arg with repl_arg in the composite pdf.
splitArg(split_arg): Build multiple clones of the same prototype. Each occurrence of split_arg is replaced with a clone of split_arg named split_arg_[MCstate], where [MCstate] is the name of the 'master category state' that indexes the clones to be built.

Example: Change the decay constant of an exponential for each run

Splitting is particularly useful when building simultaneous fits to subsets of the data sample with different background properties. In such a case, the user builds a single prototype PDF representing the structure of the signal and background and splits the dataset into categories with different background properties. Using RooCustomizer a PDF for each subfit can be constructed from the prototype that has same structure and signal parameters, but different instances of the background parameters: e.g.

...
RooExponential bg("bg","background",x,alpha) ;
RooGaussian sig("sig","signal",x,mean,sigma) ;
RooAddPdf pdf("pdf","pdf",sig,bg,sigfrac) ;
 
RooDataSet data("data","dataset",RooArgSet(x,runblock),...)
 
RooCategory runblock("runblock","run block") ;
runblock.defineType("run1") ;
runblock.defineType("run2") ;
 
RooArgSet splitLeafs;
RooCustomizer cust(pdf,runblock,splitLeafs);
cust.splitArg(alpha,runblock);
 
RooAbsPdf* pdf_run1 = cust.build("run1") ;
RooAbsPdf* pdf_run2 = cust.build("run2") ;
 
RooSimultaneous simpdf("simpdf","simpdf",RooArgSet(*pdf_run1,*pdf_run2))

If the master category state is a super category, leafs may be split by any subset of that master category. E.g. if the master category is 'A x B', leafs may be split by A, B or AxB.

In addition to replacing leaf nodes, RooCustomizer clones all branch nodes that depend directly or indirectly on modified leaf nodes, so that the input pdf is untouched by each build operation.

The customizer owns all the branch nodes including the returned top level node, so the customizer should live as longs as the cloned composites are needed.

Any leaf nodes that are created by the customizer will be put into the leaf list that is passed into the customizers constructor (splitLeafs in the above example. The list owner is responsible for deleting these leaf nodes after the customizer is deleted.

Advanced techniques

Reuse nodes to customise a different PDF

By default, the customizer clones the prototype leaf node when splitting a leaf, but the user can feed pre-defined split leafs in leaf list. These leafs must have the name <split_leaf>_<splitcat_label> to be picked up. The list of pre-supplied leafs may be partial, any missing split leafs will be auto generated.

Another common construction is to have two prototype PDFs, each to be customized by a separate customizer instance, that share parameters. To ensure that the customized clones also share their respective split leafs, i.e.

PDF1(x,y, A) and PDF2(z, A) ---> PDF1_run1(x,y, A_run1) and PDF2_run1(x,y, A_run1)

PDF1_run2(x,y, A_run2) and PDF2_run2(x,y, A_run2)

y

Double_t y[n]

Definition legend1.C:17

feed the same split leaf list into both customizers. In that case, the second customizer will pick up the split leafs instantiated by the first customizer and the link between the two PDFs is retained.

Customising with pre-defined leafs

If leaf nodes are provided in the sets, the customiser will use them. This is a complete example that customises the yield parameter, and splits (automatically clones) the mean of the Gaussian. This is a short version of the tutorial rf514_RooCustomizer.C.

RooRealVar E("Energy","Energy",0,3000);
 
RooRealVar meanG("meanG","meanG", peak[1]);
RooRealVar fwhm("fwhm", "fwhm", 5/(2*Sqrt(2*Log(2))));
RooGaussian gauss("gauss", "gauss", E, meanG, fwhm);
 
RooPolynomial linear("linear","linear",E,RooArgList());
 
RooRealVar yieldSig("yieldSig", "yieldSig", 1, 0, 1.E4);
RooRealVar yieldBkg("yieldBkg", "yieldBkg", 1, 0, 1.E4);
 
RooAddPdf model("model","model",
    RooArgList(gauss,linear),
    RooArgList(yieldSig, yieldBkg));
 
RooCategory sample("sample","sample");
sample.defineType("BBG1m2T");
sample.defineType("BBG2m2T");
 
 
RooArgSet customisedLeafs;
RooArgSet allLeafs;
 
RooRealVar mass("M", "M", 1, 0, 12000);
RooFormulaVar yield1("yieldSig_BBG1m2T","sigy1","M/3.360779",mass);
RooFormulaVar yield2("yieldSig_BBG2m2T","sigy2","M/2",mass);
allLeafs.add(yield1);
allLeafs.add(yield2);
 
 
RooCustomizer cust(model, sample, customisedLeafs, &allLeafs);
cust.splitArg(yieldSig, sample);
cust.splitArg(meanG, sample);
 
auto pdf1 = cust.build("BBG1m2T");
auto pdf2 = cust.build("BBG2m2T");

		const RooAbsCategoryLValue &	masterCat,
		RooArgSet &	splitLeafs,
		RooArgSet *	splitLeafsAll = `0`

Constructor with a prototype and masterCat index category.

Customizers created by this constructor offer both the replaceArg() and splitArg() functionality.

Parameters

[in]	pdf	Proto PDF to be customised.
[in]	masterCat	Category to be used for splitting.
[in,out]	splitLeafs	All nodes created in the customisation process are added to this set. The user can provide nodes that are taken from the set if they have a name that matches `<parameterNameToBeReplaced>_<category>`.

Note: The set needs to own its contents if they are user-provided. Use e.g.
RooArgSet customisedLeafs;

auto yield1 = new RooFormulaVar("yieldSig_BBG1m2T","sigy1","M/3.360779",mass);

customisedLeafs.addOwned(*yield1);

RooArgSet::addOwned
Bool_t addOwned(RooAbsArg &var, Bool_t silent=kFALSE) override
Add element to an owning set.
Definition RooArgSet.cxx:274
