Hi all,
fitting data to a Poisson distribution does not work as stated in the doc of fit_mle.
fit_mle
with v0.25.95 and v0.25.98
v0.25.95
v0.25.98

Other (continous) distributions I tested worked as espected (Normal, LogNormal, Gamma, Weibull, Laplace). Am I doing something wrong, is there an error in the doc or was somewhere back in history a braking chance on either the Poisson or fit_mle?

Poisson
A Poisson distribution describes counts. You can fit it on non-negative integers (Distributions.jl@0.25.95)
Distributions.jl@0.25.95
