> I have been trying to use [GLM.jl](https://juliahub.com/ui/Packages/General/GLM) to fit some logistic regression models and the fit failed. I don’t remember the exact error message but it was something about singularity.

If you can give a reproducible example and the exact error message, peopel can give you more helpful advice. Without that, it’s hard for this thread to go anywhere productive. [Please read: make it easier to help you](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757)
