I need to fit a sampling of a multidimensionnal pdf of 2 variables (x,y),
the information I have are thus under the form:
Fitting a pdf means fitting the number of events. Using MultiDimFit in my case would then mean to build an histogram and then to use MultiDimFit :AddRow by looping on the bins.
In that case I would loose the advantage of unbinned fit…
Can MultidimFit fit an unbinned sampling of a pdf ?
