How to fit asymmetric Gaussian


I am trying to fit an distribution by asymmetric Gaussian by roofit. Please some one give an example code.

Thanks in advance.

The form of the function you want to fit to this depends on what kind of distribution it is. Two examples of asymmetric distributions that might be good are the Weibull distribution, and a reversed lognormal distribution. You can see their formulas in the standard library.

Thank You very much !! I am trying with BiFurGauss function in roofit with two different sigma.
