Hi,

In Roofit, or otherwise, after fitting some data with a model/pdf, is it possible to get errors in the “shape” or “height” (and not on the parameters) of the fit result curve?

For example, if I fit (x,y) data with a pdf p, to get a result y = p(x), RooFitResult gives me errors on the parameters. What I wish to calculate is the error in p(x) at some x (which will of course can be estimated from the errors in parameters, but I wish to know if there is some function, which can directly return such an error).

Thanks,

Nikhil
