Fit data with asymmetric error bars on both axes

[Elisa-Visentin]

Hi, I have to fit a set of data points whose error bars are asymmetric on both axes (e.g., Y1+0.2-0.3, X1+0.1-0.2, Y2+0.1-0.5.....). Can iminuit face this task? How?
Thank you!

iminuit currently does not handle this case, because it is ill-defined, see section 6.3 in https://arxiv.org/pdf/1905.12362.pdf
