## Description
Using `objective='poisson'` with big weights in some cases produces very large predictions, up to $10^{252}$ times higher than the biggest example in the train dataset.
## Reproduci…

I am trying to implement the same code from R using glmnet and in Python. The issue is that I am using Poisson regression.
In R, I want to run the following regression. A vector y on 3 variables. I…

special case of #7412
some notes for implementation. looks relatively straight forward for cases with simple terms
The main problem is the correction term in objective function and score for fishe…

Since I updated on the latest R Version 4.1.0, I am not able to plot some of the compatibility intervals with `shade()` anymore e. g. in R code 4.57 (see code below).
While `shade()` does not plot t…

#### Describe the workflow you want to enable
If the target `y` is (approximately) Poisson, Gamma or else Tweedie distributed, it would be beneficial for tree based regressors to support [Tweedie dev…

Looking at the tutorials, the ordering looks a bit random. Perhaps we should reorder the tutorials, roughly in order from least to most advanced, to make it easier to understand them? I'd suggest some…
