Figure 2 – Gaussian PDF with different widths. 1 If you get a ROOT error message at this point because LineColor is not defined, you have forgotten to include 'using namespace RooFit' in your ROOT setup as was explained in Section 1. Hi I have a file containing a very complicated numerical function. I want to define this in RooFit (actually one of the dimensions of the TF2 ends up being a parameter) as a RooAbsPdf. What I have is shown below. This actually works you first have to compile the RooLS pdf (my user defined pdf), then load From : Anil Singh Date : Tue, 8 Sep 2009 18:45:24 +0500. Hi All,. This is about the convolution utilities in RooFit. I have creates detailed pdf for Z/gamma* production, including the terms for Z/gamma interference and gamma* contributions. I have methodically follwed roofit tutorials, Statistical Methods for Data Analysis. 7.

Use the same discriminating variable as the signal. ? Define the background PDF. ? RooFit defines a polynomial of order n (Pn) as. 2. P ax bx C. = +. +. C is determined from the automatic PDF. 14 Oct 2008 Here is an example of a model defined in RooFit that is subsequently used for event generation, an unbinned maximum likelihood fit and plotting. // --- Observable ---.
