RooGenericPdf Class Reference

RooGenericPdf is a concrete implementation of a probability density function, which takes a RooArgList of servers and a C++ expression string defining how its value should be calculated from the given list of servers.

A fully numerical integration is automatically performed to normalize the given expression. RooGenericPdf uses a RooFormula object to perform the expression evaluation

The string expression can be any valid TFormula expression referring to the listed servers either by name or by their ordinal list position:

RooGenericPdf("gen","x*y",RooArgList(x,y)) or RooGenericPdf("gen","@0*@1",RooArgList(x,y))

The latter form, while slightly less readable, is more versatile because it doesn't hardcode any of the variable names it expects
