Basically, I’m trying to understand how to draw a confidence band over the fitted function on a plot. I searched online and I didn’t found a lot of info, except other programs or languages that do this automatically, and [an example using GLM](https://discourse.julialang.org/t/plot-the-confidence-interval-for-a-model-fit/37767).
