Unbinned fraction fit

Dear experts,

until now I’m using the class TFractionFitter which performs a binned likelihood fit taking the statistical uncertainties of the MC templates into acccount. Now I want to perform an unbinned likelihood fit. Is there any ROOT class or ROOT package (RooFit?) which already offers this functionality? I would be glad if someone could post an example.



P.S. Is a fraction fit a la TFractionFitter possible with the RooFit package? Are there examples? I have weighted MC templates with rather limited statistics …
