I've encountered a strange issue: `abess()` does not terminate in a specific situation. The following code produces a reproducible example. It runs for at least 10 mins without termination. However, b…

Hi - I'm trying to understand whether offsets can be used for Poisson models in the natural way.
By this I mean that my observations have heterogenous "observation length", which is naturally model…

Dear authors,
I have been working with the code provided in this repository and have some concerns related to the methods and claims presented in the associated paper. Here are the specific issues …

## 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…

Noise standard deviation/variance doesn't exist for logistic or poisson regression. Seems like part of it is being computed in coef_cov_quad_form, but not being used to calculate the noise_std; wherea…

Nonnegative regression is useful in a number of contexts. For example, if one wishes to estimate the conditional variance then regressing (Y-E[Y|X])^2 on X using poisson regression makes sure the esti…

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…

My team has been working on a problem involving scattered data in a 3D space which we need to regress onto a gridded surface. We have measurement data which has noise and can not be fit by a parametri…
