I have a question regarding directly accessing the likelihood function in RooFit. I currently have my p.d.fs as RooHistPdf objects and I then use this to fit to some binned dataset. Just for sanity check and out of curiosity, I want to manually fix the values of my parameters and see what value of the likelihood comes out. For example, I want to fix par_1= x and par_2 =y and see what value of FCN I get. In this case, no fitting is being done and is therefore independent of the actual dataset I end up fitting to. Is there a way to do this? Thanks!
