I am modeling Generalised Extreme Value Distribution in PYMC3 but I keep on getting SamplingError: Initial evaluation of model at starting point failed! I am implementing my own distribution. The logp equation is the PDF of GEV. I took the inital values for the shape, location and scale parameters f…
