Heelo,
i would like to fit a 2D distribution with 2 correlated gaussians. I would like to know if this already exists as a class in RooFit. In the class reference i found:
Roo2DKeysPdf … Non-Parametric Multi Variate KEYS PDF
Sounds similar like what i want. Do i have to use this class? Does a 2D correlated gaussian PDF exists?
Best regards,
Peter
