Re: root : unbinned fit 1D

Hello Marc,

An unbinned fit to a histogram makes no sense. Presumably you mean you want to fit the data that is used to make the histogram w/o binning it.

I'm not sure if ROOT has a native unbinned fitter; you could use RooFit or you could write your own using minuit via TMinuit.

A likelihood fit to a finely binned histogram is more or less equivalent to an unbinned fit and ROOT does do that.
