Dear experts,
I am trying to fit experimental observables with a backtracking method based on RooFit. I want to know wich distribution of my 2 model input parameters represent the best my experiment. I’ve generated around 2500 events for each combination of my model parameters.
A problem for me is that I want to create a PDF mixing Integer-values observables (such as the mass or charge of a particle) with Double-values observables (such as energy of the a particle). Those observables are correlated. For the moment I’m focusing in particular on 2 observables.
1)I’ve first tried to fit my experiment with a RooAddPdf constructed from a set of RooDataHist from my model TTree, one for each input parameter couple from the model. This method isn’t working and is returning that kind of errors (where “Model” stands for the RooAddPdf):
[#1] INFO:Minization -- A total of 205 expressions have been identified as constant and will be precalculated and cached.
[#1] INFO:Minization -- A total of 205 expressions have been identified as constant and will be precalculated and cached.
[#1] INFO:Minization -- A total of 205 expressions have been identified as constant and will be precalculated and cached.

- I’ve tried another method, creating RooNDKeys of the 2 observables from the model TTree and create a RooAddPdf from them, then apply the method “fitTo” using the experimental RooDataSet. The fit is running, but the results depend a lot on the rho parameter of the bandwith of the gaussian kernels. Here are 2 (not-convincing) fit results using rho=1.0 and rho=3.0.

I would like to know if someone already tried such kind of fit, if you have any comment/remark on my methods and if there is maybe a better solution (for example maybe using RooCategory Class) ?
I am using ROOT 5.34 and can share the codes with you if you are interested and want to see in details.
Thanks a lot,
Quentin.
